Description

  The present invention relates to a management method for managing the radiation dose of radiation workers.

  Conventionally, there is a radiation management system that manages the radiation dose of radiation workers engaged in work in radiation control areas (hereinafter referred to as control areas) of radiation handling facilities such as nuclear power plants and medical facilities that use radiation such as nuclear medicine treatment. It is known (see, for example, Patent Document 1). In such a radiation management system, an integrated server for radiation management that integrates and manages a plurality of radiation handling facilities is provided, and the radiation management integrated server manages the radiation dose of radiation workers in the management area of each radiation handling facility. Has also been considered.

  By the way, a worker who works in a management area of a radiation handling facility such as a nuclear power plant needs to perform designated registration of a radiation worker. Designated registration of radiation workers is done for each radiation handling facility. Until now, if one radiation worker engaged in radiation work across multiple radiation handling facilities, the designation of the radiation handling facility (A) that was previously registered as a radiation work worker must be cancelled. The management method A was designated and registered as a radiation worker in another radiation handling facility (B) after the radiation handling facility (A) was unable to work. However, in this management method A, when working across a plurality of radiation handling facilities, cancellation of designation registration and new designation registration are repeated each time the radiation handling facility is changed. Therefore, management method B that simplifies management method A and engages in radiation work across a plurality of radiation handling facilities is considered to be a management method B that enables flexible operation by allowing multiple designation and registration of multiple radiation handling facilities. It is done.

  The entry / exit check DB 232 includes a work master table 232a, an operator master table 232b, and an entry / exit check information table 232c. The work master table 232a stores, for example, a worker ID that is identification information of a worker and a radiation management task (work title) that the worker can engage in association with each other. For example, the worker master table 232b stores the worker ID and the name of the worker in association with each other. The entry / exit check information table 232c stores, for example, the worker ID and the worker's entry / exit check information in association with each other. The entry / exit check information includes, for example, entry time, exit time, and exposure dose (daily dose, monthly dose, etc.) during a predetermined period. The data held in the work master table 232a, the worker master table 232b, and the entry / exit check information table 232c is updated every time via the communication unit 231 from the entry / exit check master DB 42 of the integrated server 4 described later. (Real time) or downloaded at a predetermined cycle (for example, a daily cycle).

  The entry check processing unit 234 performs an entry check process for the worker based on the acquired information from the entry / exit management device 21. Specifically, the entrance check processing unit 234 receives the entrance request including the worker ID from the entrance / exit management device 21, and the worker ID is engaged from the work master table 232a based on the worker ID. Extract possible work subjects. The entry check processing unit 234 transmits a work list indicating the extracted work subject to the entry / exit management device 21. The work list is displayed on the display screen of the entry / exit management device 21, for example. In the entry / exit management device 21, the work subject selected by the operator's operation is input to the entry check processing unit 234 together with the worker ID.

  Further, the entry check processing unit 234 checks the worker's entry by referring to the worker master table 232b and the entry / exit check information table 232c based on the work subject and worker ID. For example, the entrance check processing unit 234 determines the qualification based on the entrance / exit check information stored in the entrance / exit check information table 232c, and permits or rejects the entrance of the worker into the radiation control area. The entrance check processing unit 234 transmits the qualification determination result (that is, permission or rejection) to the entrance / exit management device 21.

  The entrance / exit management device 21 opens and closes the entrance / exit gate based on the entrance check result from the entrance check processing unit 234. Specifically, when permitting the worker to enter, the entrance / exit management device 21 opens the entrance / exit gate, and stores the worker ID, the entry time, the work subject, etc. in the result reflection processing unit 235 described later. Output. On the other hand, when the entry / exit management device 21 refuses the entry of the worker, the entry / exit management device 21 sounds an alarm without opening the entry / exit gate, and notifies the system management processing unit 236 described later.

  The record accumulation buffer 233 stores entry / exit information 233a, an alarm history 233b, a WBC record 233c, and a device state 233d. As the entry / exit information 233a, for example, the worker ID and the worker's entry / exit information (for example, entry time, exit time) are stored. As the alarm history 233b, for example, the worker ID of the worker who has been denied entry into the radiation control area, the date and time, and the like are stored. As the WBC record 233c, for example, a worker ID, a worker's WBC data, and the like are stored. As the device status 233d, for example, the identification information of the entry / exit management device 21 and the device status (normal or abnormal) of the entry / exit management device 21 are stored. Such a result accumulation buffer 233 is configured to be able to store the data for a predetermined period (for example, the last few days).

  The result reflection processing unit 235 performs a process of reflecting the worker's entry results or withdrawal results based on the acquired information from the entry / exit management device 21. Specifically, when the worker's entry is permitted in the entry / exit management device 21, the result reflection processing unit 235 receives the worker ID, entry time, work subject input from the entry / exit management device 21. The entry / exit area information 233a in the result accumulation buffer 233 and the entry / exit area check information table 232c in the entry / exit area check DB 232 are updated. Similarly, when a worker's withdrawal is detected in the entry / exit management device 21, the result reflection processing unit 235 is based on the worker ID, the withdrawal time, and the work subject input from the entry / exit management device 21. Thus, the entry / exit information 233a and the entry / exit check information table 232c are updated.

  When the abnormality of the entry / exit management device 21 is detected, the system management processing unit 236 updates the device state 233d of the result accumulation buffer 233 to “abnormal”. In addition, the system management processing unit 236 updates the information in the alarm history 233b when notified from the entry / exit management device 21 that the worker's entry has been rejected.

  The WBC data reflection processing unit 237 updates the information on the WBC performance 233 c based on the WBC data input from the WBC device 22.

The storage items of the work master table 42a, the worker master table 42b, and the entry / exit check information table 42c are the same as those of the work master table 232a, the worker master table 232b, and the entry / exit check information table 232c. As described above, data held in the work master table 42a, the worker master table 42b, and the entry / exit check information table 42c is sent to each radiation handling facility 2 via the communication unit 41 at a predetermined cycle (for example, one day). Downloaded at every cycle) or every update (real time).

  The record master DB 43 includes an entry / exit information table 43a, an alarm history table 43b, and a WBC record table 43c. In the entrance / exit information table 43a, alarm history table 43b, and WBC record table 43c, entry / exit information 233a, alarm record 233b, and WBC record 233c acquired from the site controllers 23 of the radiation handling facilities 2A to 2C are stored, respectively. Is done. The data held in the entry / exit information table 43a, the alarm history table 43b, and the WBC record table 43c are updated in real time every time the entry / exit information 233a, alarm record 233b, and WBC record 233c are updated in each radiation handling facility 2. The In addition, when an abnormality occurs in data communication between the integrated server 4 and the radiation handling facilities 2A to 2C, the data may be updated after recovery.

  The record reflection processing unit 44 refers to the entry / exit information table 43a of the record master DB 43 and updates an entry information table 45a, a work record table 45b, an entry record table 45c, and an evaluation dose table 45d, which will be described later. The result reflection processing unit 44 performs predetermined calculation processing on the entry / exit information acquired from the entry / exit information table 43a of the result master DB 43, and based on the calculation processing result, the entry information table 45a, work result table 45b, the entry result table 45c, and the evaluation dose table 45d may be updated.

  The entry information table 45a stores, for example, the worker ID and the worker's entry record (for example, the entry time and the withdrawal time) in association with each other. The work performance table 45b stores, for example, a worker ID and a work subject name in association with each other. The entry result table 45c stores, for example, the worker ID and the exposure dose of the worker in association with each other.

  The evaluation dose table 45d stores, for example, the worker ID, the worker's entry record, and the worker's evaluation dose in association with each other. The evaluation dose of the worker is calculated based on the entry record in the entry information table 45a, the work subject in the work record table 45b, and the exposure dose in the entry record table 45c.

  The training attendance history table 45e stores, for example, the worker ID, the training attendance date of the worker, and the facility name (participating facility) of the radiation handling facility 2 that attended the training. The health checkup reception history table 45f stores, for example, the worker ID, the health checkup date of the worker, and the facility name (reception facility) of the received radiation handling facility 2 in association with each other. The WBC examination history table 45h associates, for example, the worker ID, the examination date (WBC examination date) of the internal exposure dose by the worker's WBC device 22, and the facility name (subject examination facility) of the radiation handling facility 2 that has undergone the examination. And remember.

  The worker master table 45g temporarily cancels the designated registration in one radiation handling facility and the first management method for entering / exiting management so as to allow entry into any of a plurality of radiation handling facilities. It is an integrated worker master corresponding to the second management method for entering / exiting management so as to allow entry into a radiation handling facility. The designated registration of workers is managed for each radiation handling facility 2 in the worker master table 45g. FIG. 4 is a diagram for explaining the management items of the worker master table 45g. As shown in FIG. 4, the worker master table 45g includes “facility name”, “inter-facility transfer start date”, “inter-facility transfer end date”, “initial specified date”, and “specified date”. , “Release date”, “temporary release date”, “worker latest flag”, “facility latest flag”, and “designated flag” are stored in association with each other.

  Here, the “facility name” is identification information of the radiation handling facility 2. “Inter-facility transfer start date” means that if a worker who has been designated and registered in a specific radiation handling facility 2 is also duplicated and registered in another radiation handling facility 2, the worker in that other radiation handling facility 2 This is information indicating the registration start date. “Inter-facility transfer end date” is information indicating the registration end date of the worker at the other radiation handling facility 2.

  The “initial designated date” is information indicating the date on which a worker who is not designated and registered in any radiation handling facility 2 is designated and registered in the specific radiation handling facility 2. The “designated date” is information indicating the date when the worker is designated and registered in the radiation handling facility 2. The “cancellation date” is information indicating the designated registration cancellation date of the worker at the radiation handling facility 2. “Temporary release date” is information indicating the date of temporary release when the designated registration of the worker at the radiation handling facility 2 is temporarily released.

  The “worker latest flag” is a flag indicating the latest record of the worker at a predetermined timing. For example, “1” is set in the “worker latest flag” if the latest record of the worker at a predetermined timing is set, and “0” is set if it is not the latest record. “The latest flag for each facility” is information indicating the latest record for each radiation management facility 2 of the worker at a predetermined timing. For example, “1” is set in the “latest facility latest flag” if the latest record for each radiation handling facility 2 of the worker at a predetermined timing is set, and “0” is set if it is not the latest record. The “designated flag” is information indicating the designated registration status of the worker in each radiation handling facility 2. For example, the “designated flag” is set to “1” if the worker is designated and registered in the radiation handling facility 2, “0” if the designated registration is canceled, and “3” if the designated registration is being applied. Is set.

  The worker master table 45g will be further described in detail with reference to FIGS. The worker master table 45g corresponds to a different management method between the radiation handling facilities 2 and manages the designated registration of radiation workers for each radiation handling facility 2. FIG. 5 is a diagram for explaining the first management method, and FIG. 6 is a diagram for explaining the second management method. 5 and 6 show a record creation example of the worker master table 45g when a specific worker (hereinafter referred to as a worker α) engages in work across the radiation handling facilities 2A and 2B. Note that the data settings in FIGS. 5 and 6 are merely examples, and are not limited to the setting methods shown in FIGS.

  The first management method is a method of managing so that the worker α can enter both of the plurality of radiation handling facilities 2 when the worker α is repeatedly designated and registered in the plurality of radiation handling facilities 2 ( 5, the worker α is initially designated as the radiation handling facility 2A at timing (1), and duplicated as designated at the radiation handling facility 2B in addition to the radiation handling facility 2A at timing (2). In (3), the designation is released from the radiation handling facility 2B, and in timing (4), the designation is also released from the radiation handling facility 2A, and the worker α is initially designated in the radiation handling facility 2B in timing (5). At timing (6), the designation is canceled from the radiation handling facility 2B.

  Hereinafter, the date of timing (1) is the initial designated date A, the date of timing (2) is the duplicate designated date B, the date of timing (3) is the release date C, and the date of timing (4) The description will be made with the date as the release date D, the date of timing (5) as the initial designated date E, and the date of timing (6) as the release date F.

  At the timing (1) in FIG. 5, the worker α is initially designated as the radiation handling facility 2A. Therefore, in the worker master table 45g, the “facility name” is “radiation handling facility 2A” and “inter-facility transfer start date”. , Data 1 in which “initial specified date A” is set as “initial specified date” and “specified date” is generated. Since the data 1 is the latest data for the worker α, the “worker latest flag” of the data 1 is set to “1 (latest)”. Since the data 1 is the latest data for the worker α and the radiation management facility 2A, the “facility latest flag” of the data 1 is also set to “1 (latest)”. In addition, since the worker α is in a state of being designated and registered in the radiation handling facility 2A, the “designated flag” of the data 1 is set to “1 (designated)”.

  At the timing (2) in FIG. 5, since the worker α is designated and registered in the radiation handling facility 2B in addition to the radiation handling facility 2A, the “master name” in the worker master table 45g is “radiation handling facility 2B”. ”,“ Institution transfer start date ”and“ Designated date ”,“ Duplicated designated date B ”and“ Initial designated date ”as“ Initial designated date A ”are generated for worker α. Since the data 2 is the latest data for the worker α, the “worker latest flag” of the data 2 is set to “1 (latest)”. On the other hand, since the data 1 described above is no longer the latest data for the worker α, the “worker latest flag” of the data 1 is updated to “0 (non-latest)”.

  In addition, at the timing (3) in FIG. 5, the worker α is released from the radiation handling facility 2B. Therefore, in the worker master table 45g, the “inter-facility transfer end date” and the “release date” in the data 2 described above. "Release date C" is set. Further, the “designated flag” of the data 2 is updated to “0 (designation cancelled)”.

  In addition, at the timing (4) in FIG. 5, the worker α is also released from the radiation handling facility 2A. Therefore, in the worker master table 45g, the “inter-facility transfer end date” and the “release date” of the above data 1 are used. "Release date D" is set. Also, the “designated flag” of data 1 is updated to “0 (designation cancelled)”. Further, since the data 1 is the latest data of the worker α, the “worker latest flag” of the data 1 is updated to “1 (latest)”. On the other hand, since the data 2 is no longer the latest data for the worker α, the “worker latest flag” of the data 2 is updated to “0 (non-latest)”.

  Further, at the timing (5) in FIG. 5, the worker α is newly initially registered in the radiation handling facility 2B. Therefore, in the worker master table 45g, “radiation handling facility 2B”, “between facilities” Data 3 in which “initial specified date E” is set as “movement start date”, “initial specified date”, and “specified date” is generated. Since the data 3 is the latest data for the worker α, the “worker latest flag” of the data 1 is set to “1 (latest)”. On the other hand, since the data 1 is no longer the latest data for the worker α, the “worker latest flag” of the data 1 is updated to “0 (non-latest)”. Further, since the latest data for the worker α and the radiation handling facility 2B is data 3, the “latest flag for each facility” of the data 2 is set to “0 (non-latest)”.

  In addition, at the timing (6) in FIG. 5, the worker α is deselected from the radiation handling facility 2B. Therefore, in the worker master table 45g, the “inter-facility transfer end date” and “cancellation date” of the data 3 described above. "Release date F" is set. In addition, the “designated flag” of data 3 is updated to “0 (designation cancelled)”.

  According to the worker master table 45g, the duplicate designation of the workers α for the plurality of radiation handling facilities 2 of the first management method can be managed by grouping using the initial designated date. For example, in FIG. 5, the initial designated date of data 1 and 2 related to duplicate designation registration is the same as the initial designated date A. For this reason, data 1 and 2 related to duplicate designation registration can be grouped on the same initial designated date A. As a result, even if the workers α are designated redundantly in the plurality of radiation handling facilities 2 of the first management method, the designated registration states of the workers α for the plurality of radiation handling facilities 2 can be managed collectively. .

  In the second management method, when the worker α is designated redundantly in a plurality of radiation handling facilities 2, the designation registration in one radiation handling facility 2 is temporarily canceled and the other radiation handling facility 2 is engaged. This is a management method so that the person α can enter. The second management method is different from the first management method in that a new radiation handling facility 2 cannot be designated and registered unless the designated registration of the radiation handling facility 2 designated and registered first is temporarily canceled.

  In FIG. 6, the worker α is initially designated as the radiation handling facility 2A at the timing (1), temporarily deregistered from the radiation handling facility 2A at the timing (2), and then overlapped with the radiation handling facility 2B. Registered as specified. In addition, when the designated α is released from the radiation handling facility 2B at the timing (3), the worker α is redesignated and registered at the radiation handling facility 2A, and at the timing (4), the designated registration is also released from the radiation handling facility 2A. The worker α is initially designated and registered in the radiation handling facility 2B at timing (5), and is deregistered from the radiation handling facility 2B at timing (6).

  Hereinafter, the date of timing (1) is the initial designated date A, the date of timing (2) is the temporary release date B and the duplicate designated date C, and the date of timing (3) is the redesignated date D and released. The description will be made with the date E, the date of timing (4) as the release date F, the date of timing (5) as the initial designated date G, and the date of timing (6) as the release date H. In the following, description will be made focusing on differences from the first management method.

  At timing (1) in FIG. 6, data 1 is generated as in the first management method. At the timing (2) in FIG. 6, since the worker α is temporarily deregistered from the radiation handling facility 2A, the “temporary cancellation date” of the data 1 is set to the “temporary cancellation date B”. Since the worker α is only temporarily deregistered from the radiation handling facility 2A, the “designated flag” of the data 1 is maintained at “1 (designated)”.

  At the timing (3) in FIG. 6, the worker α is re-designated and registered in the radiation handling facility 2A that has been temporarily deregistered. Therefore, in the worker master table 45g, “radiation handling facility 2A” ”,“ Transfer date between facilities ”, and“ redesignated date D ”as“ designated date ”, data 3 is generated. Since the data 3 is the latest data for the worker α, the “worker latest flag” of the data 3 is set to “1 (latest)”. On the other hand, since the data 1 is not the latest data for both the worker α and the radiation handling facility 2A, the “worker latest flag” and the “facility latest flag” of the data 1 are updated to “0 (non-latest)”. The

  At the timing (4) in FIG. 6, the worker α is also released from the radiation handling facility 2A, and therefore, in the worker master table 45g, the “inter-facility transfer end date” and “release date” of the data 3 described above. "Release date F" is set. In addition, the “designated flag” of data 3 is updated to “0 (designation cancelled)”. Further, at the timing (4), the “inter-facility transfer end date” of the data 1 is set to a date obtained by subtracting one day from the “redesignated date D”, and the “designated flag” of the data 1 is set to “0 (designated). Canceled) ”. At timing (5) in FIG. 6, data 4 is generated and updated as in the first management method.

  Also by the worker master table 45g, the duplicate designation registration of the workers α for the plurality of radiation handling facilities 2 of the second management method can be managed by grouping using the initial designated date. For example, in FIG. 6, the initial designated dates of data 1 to 3 relating to duplicate designation registration are the same as the initial designated date A. Therefore, the data 1 to 3 related to the duplicate designation registration can be grouped on the same initial designation date A. As a result, the designated registration status of the worker α for the plurality of radiation handling facilities 2 is collectively managed even when the worker α is designated for multiple registration according to the plurality of radiation handling facilities 2 of the second management method. it can.

  According to the worker master table 45g described above, it is possible to manage duplication designation registration of the worker α in both cases of the first and second management methods. For this reason, it is not necessary to provide a management table for duplication designation registration management for each different management method, and the mounting load related to duplication designation registration management can be reduced.

  The screen processing unit 46 receives an input instruction from the terminal 5 and / or the terminal 24, refers to the totaling master DB 45, and totals the exposure dose of the worker α under various conditions. The screen processing unit 46 outputs the counting result to the terminal 5 and / or the terminal 24. In the terminal 5, the total result is displayed on the display screen.

  The personal totalization processing unit 47 totalizes the entrance / exit check information of the worker α in accordance with the update of the totalization master DB 45, and reflects the total entry / exit check information in the entrance / exit check information table 42c. The entry / exit check information reflected in the entry / exit check information table 42c is downloaded to the site controllers 23 of the radiation handling facilities 2A-2C at every update (real time) or at a predetermined cycle.

  Next, the operation of the radiation management system 1 configured as described above will be described. First, the operation of counting the exposure dose of the worker α, second, the operation of reflecting the entrance / exit area check information of each radiation handling facility 2, and third, between the integrated server 4 and each radiation handling facility 2 The operation at the time of occurrence of an abnormality in data communication, and fourthly, the operation at the time of restoration of data communication between the integrated server 4 and each radiation handling facility 2 will be described.

  First, the operation of counting the exposure dose of the worker α will be described. When the designated condition of the worker α is input from the terminal 24 via the terminal 5 or the wide area network connected to the integrated server 4, the screen processing unit 46 of the integrated server 4 performs the aggregation based on the specified condition (1). Total data is acquired from the master DB 45. The aggregated data is output from the screen processing unit 46 to the terminal 24 via the terminal 5 or the wide area network, and displayed on the display unit (not shown) of the terminal 24 via the terminal 5 or the wide area network. With reference to FIG. 5 and FIG. 7, the counting operation based on such a predetermined designated condition will be described in detail. FIG. 7 is a diagram illustrating a relationship between predetermined designation conditions and data in the worker master table 45g.

  In the following, an example in which the data of the worker master table 45g is managed by the management method 1 (see FIG. 5) will be described. However, the data can also be appropriately applied to cases where the data is managed by the management method 2 (see FIG. 6). is there. Further, it is assumed that the current date X is between timings (5) and (6) in FIG. 5, and the past date Y is between timings (2) and (3).

  The designated condition (1) shown in FIG. 7 is a condition for acquiring the radiation dose of the worker α at the specific radiation handling facility 2 designated and registered on the current date X (here, 2B). In such a designated condition (1), the “facility name” of the worker master table 45g is “radiation handling facility 2B”, the “start date of movement between facilities” is the date before the current date X, “Inter-facility transfer end date” is not set or is the date after the current date X, “Facility latest flag” is “1 (latest)”, and “designated flag” is “1 (designated)” ”Is required. As shown in FIG. 5, since the worker α is designated and registered in the radiation handling facility 2B on the initial designated date E on the current date X, the personal totalization processing unit 47 displays the data as data satisfying the designated condition (1). Data 3 of timing (5) is acquired from the worker master table 45g shown in FIG. The personal totalization processing unit 47 refers to the work result table 45b, the on-site result table 45c, and the evaluation dose table 45d based on the data 3 acquired from the worker master table 45g, and at the current date X in the radiation handling facility 2B. The exposure dose of worker α is tabulated. According to such a designated condition (1), it becomes possible to collect the radiation dose at the radiation handling facility 2 (here, 2B) where the worker α currently enters.

  The designated condition (2) shown in FIG. 7 is a condition for obtaining the total exposure dose of the worker α at a specific radiation handling facility 2 (in this case, 2B) that has been designated or registered on the past day Y. It is. In such a designated condition (2), the “facility name” of the worker master table 45g is “radiation handling facility 2B”, the “start date of movement between facilities” is the date before the past date Y, and “ It is requested that “the transfer end date between facilities” is not set or is a date after the past date Y. In addition, in the designation condition (2), the “designated flag” is “1 (designated)” or “0 (designated)” so that the data of the initial designated date that has already been undesignated is also subject to aggregation. Request. As shown in FIG. 5, since the worker α is designated and registered in the radiation handling facility 2B on the initial designated date A on the past date Y, the personal totalization processing unit 47 displays the data satisfying the designated condition (2) as data that satisfies the designated condition (2). Data 2 of timing (2) is acquired from the worker master table 45g shown in FIG. As described above, the personal tabulation processing unit 47 tabulates the exposure dose of the worker α on the past date Y in the radiation handling facility 2B based on the data 2. According to such a designated condition (2), the total exposure dose of the worker α in a specific radiation handling facility 2 (here, 2B) that has entered in the past predetermined date can be tabulated.

  The designated condition (3) shown in FIG. 7 is a condition for obtaining the total exposure dose of the worker α at all the radiation handling facilities 2 that have been designated for duplicate registration on the current date X. Such a designation condition (3) is different from the designation condition (1) in that the “facility name” in the worker master table 45g is not limited. As shown in FIG. 5, since the worker α is designated and registered only at the radiation handling facility 2B on the current date X, the personal totalization processing unit 47 acquires the data 3 and based on the data 3 on the current date X. Total exposure doses of workers α. According to the designated condition (3), it is possible to tabulate the current exposure dose used for the worker α entry check process. More specifically, since it is possible to obtain the total exposure dose of the worker α at the plurality of radiation handling facilities 2 that are currently designated and registered on the day X, the specific radiation of the worker α is based on the total exposure dose. It is possible to determine whether or not to permit entry into the (radiation) management area of the handling facility 2.

  The designated condition (4) shown in FIG. 7 is a condition for acquiring the total exposure dose of the worker α at all the radiation handling facilities 2 designated or canceled on the past day Y. Such a designation condition (4) differs from the designation condition (2) in that the “facility name” in the worker master table 45g is not limited. As shown in FIG. 5, since the worker α is designated and registered in the radiation handling facilities 2 </ b> A and 2 </ b> B on the past day Y, the personal totalization processing unit 47 acquires data 1 and 2, and based on the data 1 and 2 The total exposure dose of worker α on the past day Y is then tabulated. According to the specified condition (4), it is possible to tabulate the past total exposure dose used for the entry check process of the worker α.

  The designated condition (5) shown in FIG. 7 is a condition for acquiring the latest data of the worker α regardless of the radiation handling facility 2. Such a designation condition (5) requires that the “worker latest flag” in the worker master table 45g is “1 (latest)”. For example, during the timings (2) and (3) in FIG. 5, since the worker α is designated to be duplicated in the radiation handling facilities 2A and 2B, the personal totalization processing unit 47 sets the data satisfying the designated condition (5). Data 2 is acquired. According to the specified condition (5), when the worker α is registered in a plurality of radiation handling facilities 2, the exposure dose at the radiation handling facility 2 where the worker α currently enters can be tabulated.

  The designation conditions for the worker α are not limited to the above-described designation conditions (1) to (5). “Facility name”, “Inter-facility transfer start date”, “Inter-facility transfer end date”, “Initial specified date”, “Specified date”, “Release date”, “Temporary cancellation date”, “ The specified condition may be specified by specifying at least one of the values of the latest worker flag, the latest flag for each facility, and the “designated flag”.

  As described above, the designated registration of the worker α is collectively managed by the worker master table 45g corresponding to the different management methods 1 and 2, so that the worker α has a plurality of radiation handling facilities 2 having different management methods. Even when designated registration is performed across the two, the designated registration of the worker α can be extracted from the worker master table 45g under predetermined designated conditions, and the exposure dose of the worker α can be easily tabulated on the designated registration basis.

  Secondly, the operation of reflecting the entrance / exit area check information in the radiation handling facility 2 will be described. FIG. 8 is a diagram for explaining the operation of reflecting the entry / exit check information. In FIG. 8, when the entry / exit result data of the worker α is updated in the site controller 23 of the radiation handling facility 2A, the worker is transferred to the site controllers 23 of the radiation handling facilities 2B and 2C via the integrated server 4. α entry / exit data is reflected.

  As shown in FIG. 8, the result reflection processing unit 235 of the radiation handling facility 2 </ b> A stores the entry / exit result data input from the entry / exit region management device 21 in the result accumulation buffer 233, via the communication units 231 and 41. And stored in the entry / exit information table 43a of the result master DB 43 of the integrated server 4. The entry / exit result data includes, for example, the worker ID (here, the ID of the worker α) and the entry result of the worker α (2011/2/2 10: 00 to 2011/2/2 11). : 00) and actual dose (0.01). Note that the entry / exit result data may include the work content of the worker α.

  When the entry / exit information table 43a is updated as described above, the record reflection processing unit (not shown), based on the updated entry / exit record data of the worker α, the entry information table of the master DB 45 for aggregation. 45a, work result table 45b, on-site result table 45c, and evaluation dose table 45d are updated. The personal totalization processing unit 47 generates entry / exit check information for the worker α based on the information on the worker α stored in the totalization master DB 45.

  In FIG. 8, the entry / exit check information is generated based on the worker α information extracted from the worker master table 45g, the WBC test history table 45h, the health check test history table 45f, and the education attendance history table 45e. . The generated entry / exit check information is stored in the entry / exit check information table 42c of the entry / exit check master DB 42 by the personal totalization processing unit 47, and is connected to the radiation handling facilities 2A to 2C via the communication units 41 and 231. This is reflected in the 2C entry / exit check information table 232c.

  As described above, when the entry / exit results of the worker α are updated in the specific radiation handling facility 2, the entry / exit check information used in each radiation handling facility 2 can be updated in real time.

  Thirdly, the operation when an abnormality occurs in data communication between the integrated server 4 and the radiation handling facility 2 will be described. FIG. 9 is a diagram for explaining an operation when an abnormality occurs in data communication between the integrated server 4 and the radiation handling facility 2. Note that FIG. 9 illustrates a case where an abnormality occurs between the integrated server 4 and the radiation handling facility 2A, but the same applies when an abnormality occurs between the integrated server 4 and the radiation handling facility 2B or 2C. It is possible to operate. In FIG. 9, a part of the functional configuration of the radiation management system 1 described with reference to FIGS. 3A and 3B is omitted, but the functional configuration (not shown) may be included. 9 includes the secondary performance reflection processing unit 238 and the tabulation DB 239 (not shown in FIG. 3A), the site controller 23 of FIG. 3A may include these configurations.

  When an abnormality occurs between the integrated server 4 and the radiation handling facility 2 </ b> A, the site controller 23 of the radiation handling facility 2 </ b> A cannot download master data for entrance / exit check from the integrated server 4. For this reason, the site controller 23 itself generates entry / exit check information based on the entry / exit result data from the entry / exit management device 21. Specifically, as shown in FIG. 9, the secondary record reflection processing unit 238 of the site controller 23 uses the entry / exit information 233a stored in the record storage buffer 233 as the entry of the tabulation DB 239 in its own device. It is reflected in the information table 239a. When there is an entry request from the entry / exit management device 21, the entry check processing unit 234 refers to the entry information table 239a of the tabulation DB 239 in addition to the entry / exit check DB 232 and is engaged. Check the entrance of the person α.

  As described above, even when a data communication abnormality occurs between the integrated server 4 and the radiation handling facility 2A, the site controller 23 stores the entry / exit information of the worker α in the tabulation DB 239 in its own device. The entrance / exit check of the worker α is performed based on the entrance / exit information. As a result, even if the data for the entry / exit check DB cannot be downloaded from the integrated server 4, the worker α can appropriately perform the entry / exit check.

  Fourthly, the operation at the time of restoration of data communication between the integrated server 4 and the radiation handling facility 2 will be described. FIG. 10 is a diagram for explaining an operation at the time of restoration of data communication between the integrated server 4 and the radiation handling facility 2. In addition, although FIG. 10 demonstrates the case where abnormality is recovered | restored between the integrated server 4 and the radiation handling facility 2A, it is the same also when abnormality between the integrated server 4 and the radiation handling facility 2B or 2C is recovered. It is possible to operate.

  FIG. 10A is a diagram for explaining an operation of reflecting the entry / exit results when data communication is restored. As shown in FIG. 10A, when the data communication between the integrated server 4 and the radiation handling facility 2A is restored, the entrance / exit information stored in the result storage buffer 233 of the site controller 23 is stored in the communication units 231 and 41. And reflected in the results master DB 43 of the integrated server 4.

  FIG. 10B is a diagram for explaining the operation of reflecting the entry / exit check information when data communication is restored. With the update of the result master DB 43 in FIG. 10A, the tabulation master DB 45 is updated. Along with this, as shown in FIG. 10B, the contents of the entry / exit check master DB are also updated. In order to reflect these update contents, the update difference is transmitted to the site controller 23 via the communication unit 41. In the site controller 23, the update difference received by the communication unit 231 is reflected in the entry / exit check DB. As described above, when the data communication is restored, the master data of the integrated server 4 and the slave data of the site controller 23 are equalized, so that the worker's entry / exit check can be appropriately performed.

  FIG. 10C is a diagram for describing an operation of reflecting management information when data communication is restored. As the result master DB 43 in FIG. 10A is updated, the integrated server 4 also updates management information for an entrance check in the site controller 23. Such management information is held in the entry / exit check master DB 42 and is reflected in the entry / exit check DB 232 via the communication unit 41 and the communication unit 231.

  In this way, when data communication is restored between the integrated server 4 and the radiation handling facility 2A, data equalization is achieved between the integrated server 4 and the radiation handling facility 2A. Therefore, the entrance / exit check can be appropriately performed before and after the recovery.

  In addition, this invention is not limited to the said embodiment, It can change and implement variously. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited to this, and can be appropriately changed within a range in which the effect of the present invention is exhibited. In addition, various modifications can be made without departing from the scope of the object of the present invention.
