At this time, the statistical data of the control center 50 may include accumulated data such as a time period unit, a time unit, a day unit, a week unit, and a monthly unit.

The statistical data thus obtained can be utilized as basic data in the comparative analysis process of the control center 50.

That is, the control center 50 may further include a comparison analysis server 510 for analyzing the exposure level for each worker through the statistical data stored in the management database 500 as shown in FIG. 6 , The comparative analysis server 510 can compare 'normal' or 'dangerous' level to the general worker by comparing and analyzing the predetermined reference exposure dose value and the operator's exposure dose value, and more preferably, By providing numerical values of the exposure dose for workers classified as risk groups, accurate exposure control of the operator can be achieved.

7, the team terminal 30 according to an embodiment of the present invention further includes a comparison analysis module 320 and an output module 340 to calculate the exposure dose value of a general worker belonging to the team And to display a risk alert for a general worker at a risk level target.

First, the control center 50 can transmit the cumulative exposure dose value of the general worker belonging to each team and the threshold value of the prescribed exposure dose value to the team terminal 30 through the integrated data logger 40.

Herein, the cumulative exposure dose value of the general worker may be a cumulative exposure dose value until the next day, which is statistically calculated by the control center 50. The threshold value of the prescribed exposure dose value may be calculated by using the exposure Dose value.

The terminal 30 according to the team stores the data transmitted through the integrated data logger 40 in the memory 310 and transmits the cumulative exposure dose value of the general worker belonging to the team terminal 30 and the dose detection module 330, It is possible to estimate the radiation dose value of each worker in real time by adding the radiation dose values in the unit worksite 10 to be detected.

The comparison analysis module 320 of the terminal 30 according to the team can compare and compare the estimated exposure values of the general worker with the threshold values of the exposure values stored in the memory 310 in real time.

The output module 340 of the terminal 30 according to the team can output a danger warning to the general worker who exceeds the threshold value as a result of the comparison analysis of the comparison and analysis module 320. [

For example, the output module 340 may be configured as one of a speaker 341 and a display 342, and the output module 340 may be a speaker 341, or a visual alert guide through the display 342, for example.

FIG. 1 is a flowchart illustrating a method for managing a non-management worker in a radiation environment of the present invention, FIG. 2 is a flowchart illustrating a process of calculating a radiation dose value using position information of an operator according to an embodiment of the present invention, 3 is a flowchart illustrating a process of determining a radiation exposure level of an operator according to an embodiment of the present invention.

A management method (hereinafter, referred to as 'management method') for a non-management worker in the radiation environment of the present invention, which is implemented through the above-described embodiments, is a method in which a terminal for each team, (S200) of detecting and storing a real time radiation dose value at a unit work site in each team in the team terminal (S200), and transmitting the radiation dose value data for each team stored in the team to the control center (S300) to the control center.

At this time, data transmitted from the terminal for each team to the control center may be implemented by an integrated data logger capable of performing a mediation function of data communication as described in the embodiment.

The control center receives data collected from one or more team terminals and calculates a representative radiation dose value for each unit work site for each team and estimates an exposure value of a general worker belonging to each team (S400) And the like.

At this time, in step S200, the radiation dose value of the unit work site and the position information of the worker belonging to the unit work site can be collectively collected. First, the terminal for each team identifies a plurality of general workers belonging to the team (S210) And real-time position data for each general worker is collected and stored (S220)

The collection of such position data can be realized through the personal terminal which the operator wears or carries as described above.

As the location data can be collected, the control center analyzes the travel path of the general worker using the location information of the general worker for each team included in the data of the terminal for each team delivered (S410)

Meanwhile, in analyzing the exposure dose value of the worker, the control center performs a process of specifying a representative worker for each team using the movement path of the general worker analyzed by the control center (S420).

Here, the process of identifying the representative worker for each team will be described. First, the control center identifies a team that performs a non-destructive inspection schedule among a plurality of teams using the inputted work instruction sheet data. The control center analyzes the movement path of the general worker for each team, selects the general worker located nearest to the team performing the non-destructive inspection schedule, and specifies the general worker as the representative worker.

Then, the control center calculates the representative exposure dose value of the representative worker by identifying the separation distance from the terminal for each team through the position data of the representative worker of each team and applying the separation distance as an input variable (S430) The representative exposure dose value of the representative worker of each team is defined as the exposure dose value of other general workers belonging to each team (S440)

Meanwhile, the control center performs a process of storing statistical data obtained by statistically processing not only the representative radiation dose value data of the unit work site of each team and the general worker's exposure dose data but also the management database (S450).

The statistical data thus statistically processed can be used in the comparative analysis process of the control center. The control center can calculate a predetermined reference exposure dose value, for example, a normal exposure dose value and a previously-calculated general worker's exposure dose value Normal "or" dangerous "level for each general worker (S470)

That is, as shown in FIG. 3, if the radiation dose value of the statistical data does not exceed the reference radiation dose value (S482), the control center can determine the target worker as a normal level, and the radiation dose value If the reference dose exceeds the reference dose (S481), the target worker may classify the worker as a radiation risk level, classify it as a risk group, and perform a follow-up process such as limiting the worker's access to the site. S490)

Meanwhile, in the management method according to an embodiment of the present invention, the exposure dose value of the general worker of each team belonging to each team is monitored using the radiation dose value detected in real time through not only the control center but each team terminal located at each unit work site And for general workers exceeding the predetermined threshold value, an alarm notifying the danger can be outputted.

Specifically, in step S100, the control center transmits a cumulative exposure dose value of a general worker and a threshold value of a prescribed exposure dose value to a terminal for each team. In step S200, the terminal for each team performs a process of estimating an exposure dose for each general worker by adding the cumulative exposure dose value of the general worker belonging to the team and the radiation dose value of the unit worksite detected in real time.

Also, a threshold value of the exposure dose value stored in the memory is compared and analyzed in real time, and the danger alert is output to the general worker exceeding the threshold value as a result of the comparison analysis .

In this case, it is natural that the danger warning can be expressed visually or audibly by an output means such as a speaker or a display.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
