Description

  The present invention relates to a data collection method and a data collection system used for data collection when an environmental sample is collected, pretreated and sample-prepared, and the prepared measurement sample is measured to analyze the environmental sample.

Collect environmental samples such as air, water, soil, and plants for detection of harmful substances in the environment, environmental monitoring, and radioactivity monitoring, analyze the collected environmental samples, and collect toxic substance concentration data and radiation in the environment, etc. In order to accumulate data such as nocturnal nuclides and their intensities and to monitor seasonal changes, secular changes, sudden accidents, etc., it is necessary to measure and analyze a huge number of environmental samples on a regular basis.
However, environmental sample collection environment data, for example, location information is not only latitude and longitude altitude data, but also information on geological features such as paddy fields, upland fields, rivers, beaches, and weather information at the time of collection (for example, temperature, Atmospheric pressure, humidity, etc.) are also required.
Also, it is necessary to record information such as the shape and state of the collected sample itself, and to record data necessary for interpreting the final measurement / analysis result at the time of collection according to the collected sample.

Furthermore, the collected environmental sample needs to be converted into a form convenient for measurement and analysis or separated and concentrated, and pretreatment and sample preparation suitable for each environmental sample are performed. A record of pretreatment and sample preparation should be kept for each environmental sample, indicating that it is a result of measurement and analysis performed by appropriate processing, and maintaining the quality of the measurement and analysis results.

It is possible to provide a data collection method and data collection system capable of consistently managing time information, sample processing information, and measurement result information.

First, the purpose of environmental sample collection and measurement / analysis will be described.
<< Purpose of environmental sample collection, measurement and analysis >>
In the environment, artificial synthetic chemicals, artificial nuclear materials, etc. that do not exist in nature are diffused, and even a trace amount can cause harm by accumulating in the human body. Therefore, the amount of these substances is measured by collecting environmental samples such as air, soil, lakes, rivers, and sea water, as well as plants, animals, and shellfish that serve as human food. It is important.

For example, referring to FIG. 1, an outline of the flow from collection of an environmental sample to measurement / analysis will be described with reference to FIG. When measuring the radioactivity present in the living environment, for example, [Step S1] Collect environmental samples such as airborne dust including liquid, solid, and aerosol every month for a certain period of time (specimen) [Step S2] Pretreatment of the environmental sample such as filtration, ashing, dissolution, evaporation to dryness, etc., if necessary, and [Step S3] Sample of coprecipitation drying, filter separation, etc. Prepare (Step S4) and measure with a radiation detector, specify the radionuclide based on the type of radiation and the energy of the emitted radiation, and determine the radioactivity intensity (qualification and quantification of α-destructive substances) analysis). (Step S5) Further, using the result, for example, from the radioactivity measurement result of airborne dust, the amount of internal exposure caused by human breathing is evaluated, and the presence or absence of an artificial element generated by a nuclear test is determined. Check (analysis evaluation).
In the step of sample preparation in [Step S3], chemical separation is performed, and a liquid scintillator is mixed as necessary to prepare a measurement sample (chemical separation, liquid scintillation mixing), and in the step of measurement in [Step S4] In some cases, radiation measurement using a measurement counter or ICP-MASS (Inductively Coupled Plasma-Mass Spectrometry) measurement is performed.

Since such environmental radioactivity measurement has seasonal variations, it is necessary to eliminate the influence of the environmental radioactivity and determine the presence or absence of abnormalities by monitoring the temporal change in environmental radioactivity over a long period of time.
In addition, in the investigation of the presence of radioactive releases into the atmosphere by nuclear facilities and nuclear tests, and the presence of radioactive releases into lakes, rivers and sea water, accumulation in plants, seafood, seaweeds, soil and Taking into account the accumulation effect on sludge etc. in the bottom of the water, it is necessary to collect environmental samples over a long period and accumulate the results of radioactivity measurement.

As described above, measurement of environmental radioactivity requires collection of a large number of environmental samples, measurement / analysis thereof, and accumulation of measurement / analysis results.
Then, by analyzing and evaluating the changes over time of the accumulated measurement and analysis results at each observation point, it is possible to detect abnormalities at specific observation points, and by comparing the measurement and analysis results between observation points, Specificity of environmental radioactivity at points can be analyzed and evaluated.
In other words, environmental radioactivity is affected by weather such as volcanic eruptions, yellow sand, and precipitation, and is not necessarily affected only by radioactive emissions from nuclear facilities and nuclear tests.

<Data collection system>
Hereinafter, a data collection system according to an embodiment of the present invention will be described with reference to the drawings, taking as an example the case of measuring and analyzing the radioactivity of a large amount of environmental samples as described above.

(Overview)

The data collection system 500 includes an environmental sample collection point 100, an analysis center 200, and an overall management center 300 as a spatial arrangement configuration. Then, the operator 18A carries the portable terminal 2 to the environmental sample collection point 100, and various kinds of information associated with the collection of the environmental sample 13A are analyzed from the portable terminal 2 through the network 4 having the radio base station 3. The data is transmitted to 200 analysis center servers (data collection servers) 6.
Although the environmental sample has various forms, here, a leaf vegetable sample 13A described later is shown as an example.
The collection operator 18A puts the collected environmental sample 13A into the collection container 11A and brings it to the analysis center 200 with the transfer card 17 attached.

In the analysis center 200, the environmental sample 13A brought in by a plurality of measurement / analysis workers 18B is flowed through, for example, preprocessing, sample preparation, measurement / analysis, and report creation of measurement / analysis results. Share and do. The measurement / analysis result is stored in the database 6a of the analysis center server 6 with work record information at each stage such as pre-processing, sample preparation, measurement / analysis and the like.
Then, the management worker 18C, which is different from the worker 18B who performed the work of each stage such as acceptance of the environmental sample, pre-treatment, sample preparation, measurement / analysis, etc., provides various information, pre-treatment, and sample accompanying the collection of the environmental sample 13A. The work record information at each stage such as preparation, measurement / analysis, etc. is inspected, and if there is no problem in the work at each stage, the measurement / analysis result is transmitted to the central server 1 of the overall management center 300 via the network 4. And stored in the database 1a.

In the central management center 300, the central server 1 receives the measurement / analysis result report transmitted from each analysis center 200, stores it in the database 1a, and if the environmental sample is a continuous monitoring point, that point. New plot data of the time-series display graph is added as new additional data. In addition, the nearest measurement result from the present to the point of going back a predetermined period is displayed numerically on the map. These measurement results will be made public and available to local government agencies and researchers.
Hereinafter, the data collection method at the environmental sampling point 100 and the analysis center 200 will be described in detail.

(Data collection at environmental sampling points)
Next, a data collection method at the environmental sampling point 100 will be described with reference to FIGS.
FIG. 3 is a block diagram showing an outline of the functional configuration of the mobile terminal used when collecting environmental samples, and FIG. 4 is a diagram for explaining a method of collecting various information by the mobile terminal. As shown in FIG. 3, the portable terminal 2 includes a CPU, a memory and peripheral circuits (not shown), a camera lens 23, an operation unit 25 having various keys 25a, a display unit 27 using liquid crystal, and antennas 21A, 21B, and 21C. I have. The CPU includes a control unit 31 that controls the entire portable terminal 2 as a functional configuration, a camera unit 33 that converts an image obtained through the camera lens 23 into image information that is electronic information, and an antenna 21A according to a program stored in the memory. Position information by receiving signals from a GPS (Global Positioning System) satellite via an RFID tag reader / writer (RFID tag R / W) 35 and an antenna 21B communicating with the RFID tags 12A and 12P (see FIG. 2) A GPS unit 37 that calculates and acquires latitude, longitude, and altitude, and a communication unit 39 that can communicate with the radio base station 3 (see FIG. 2), the weather measurement device 41, and the thermometer 43 via the antenna 21C. is doing.
The shape of the portable terminal 2 is convenient in the form of a folding cellular phone as shown in FIG.

  The camera lens 23 and the camera unit 33 are the imaging means in the claims, the RFID tag R / W 35 is the RFID tag reader, the GPS unit 37 is the position information acquisition unit, the communication unit 39 is the communication unit, and the weather measurement device 41 is the weather information. It corresponds to each acquisition device.

The control unit 31 controls the various functional units in response to the operator 18A operating the operation unit 25.
The image passing through the camera lens 23 is controlled by the control unit 31 through the operation of the operation unit 25 as in the case of the camera-equipped mobile phone, is captured by the camera unit 33, and is stored in a memory (not shown). The image information acquired as necessary is displayed on the display unit 27 by the operation of the operation unit 25 and can be confirmed by the operator 18A.
For example, as shown in FIG. 4, there is a stream 121 in the foreground, and a vegetable field 123 in which leafy vegetables 125 are planted is spread, and the leafy vegetables 125 are used as an environmental sample 13A, and the soil in the field is used as an environmental sample 13B. When the water of the brook 121 is collected as the environmental sample 13C, according to the operation of the operation unit 25 of the operator 18A, the state of the collection point, the state of the vegetables 125, the granularity and color of the soil, the state of the brook 121, etc. Are stored in the memory as image information.

Further, according to the operation of the operation unit 25 of the operator 18A, the latitude, longitude, altitude (GPS location information) of the current position is acquired by the GPS unit 37, and the temperature measurement device 41 that measures the temperature, atmospheric pressure, and humidity is used. The measurement values (meteorological information) are acquired via the communication unit 39 and are taken into the respective memories. Measurement values such as the water temperature of the thermometer 43 and the underground temperature are taken into the memory via the communication unit 39 as necessary.
Incidentally, the meteorological measurement device 41 has a display unit 41a for displaying measurement values, and the thermometer 43 has a bar-shaped sensor unit 43a and a display unit 43b for displaying measurement values. When the meteorological measurement device 41 and the thermometer 43 are activated, the measured value is automatically transmitted as a weak radio wave and a digital signal with an identification code attached to the measured value, and the signal is transmitted via the communication unit 39 on the portable terminal 2 side. , And the control unit 31 discriminates the measured value of the signal by the identification code and displays it on the display unit 27. The operator 18A confirms that the displayed measurement value (other measurement information) is stable, that is, the measurement value that has reached the equilibrium state, and operates the operation unit 25 to receive the identification code. Attach each measured value to the memory.

Next, the operator 18A operates the operation unit 25 to activate the RFID tag R / W 35, and from the RFID tag 12P embedded in his / her carrying employee card 19 (see FIG. 2), ID information (person in charge) Name information) and read it into memory. Similarly, the ID information (collection container ID) of the RFID tag 12A attached to each collection container 11A, 11A, 11B containing the environmental samples 13A, 13B, 13C is similarly taken into the memory.
Incidentally, the RFID tags 12A and 12P are read-only RFID tags, and an identification code (ID information) is written at the time of manufacture. Therefore, the ID information of the RFID tag 12P is associated with necessary data such as the employee name in advance and registered in the database 6a of the analysis center server 6 to identify the worker 18A. Since the RFID tags 12A attached to the collection containers 11A, 11A, and 11B are written with different ID information, the containers can be individually identified.

Thereafter, the operator 18A operates the operation unit 25 to input a customer code, an order code, etc. from the operation unit 25 as necessary. The acquired image information, GPS location information, weather information (temperature, atmospheric pressure, Humidity), other measurement information (for example, water temperature, underground temperature, etc.), collection date and time information are labeled with the worker information and collection container ID, and the radio base station 3 (see FIG. 2) is labeled via the communication unit 39. ), Transmitted to the analysis center server 6 of the analysis center 200 via the network 4, and stored in the database 6a.
Incidentally, the collection date and time information can be easily generated by a function similar to the calendar / clock function of a normal mobile phone or personal computer.

  Note that text information and voice information may be added to the information sent from the mobile terminal 2 to the analysis center 200. In the case of character information, it can be input from the operation unit 25 by operating the key 25a. In the case of audio information, a small microphone 24 is stored in the portable terminal 2, an audio information acquisition unit 34 as a functional configuration unit that converts an audio signal acquired by the microphone 24 into audio information of a digital signal and takes it into the memory, and is stored in the memory. What is necessary is just to provide the audio | voice output part 36 as a function structure part which converts the audio | voice information into an audio | voice signal, and the speaker 26. FIG. Also when transmitting the character information and the voice information to the analysis center server 6, the worker information and the collection container ID are labeled and transmitted.

  As described above, when the environmental sample 13 (collectively referred to as the environmental sample 13 when it is not necessary to distinguish the environmental samples 13A, 13B, and 13C), the operator 18A needs almost no handwriting input. The state of the collection point 100 and the state of the collected environmental sample 13 can be recorded as image information. If necessary, the place name and additional information can be recorded as audio information, and labeled with the worker information and the collection container ID. By transmitting to 200, simple data collection can be performed.

Further, the customer, the environmental sample collection point, and the state of the environmental sample (leaf vegetables, soil) used by the analyst 18B (see FIG. 2) of the analysis center 200 to identify the environmental sample 13 for each of various processes after the environmental sample 13 is collected. , Water, etc.) instead of a paper-made transfer card that has been written in a conventional handwritten manner, an electronic paper type transfer card 17 is used, and the same information as that transmitted from the portable terminal 2 to the analysis center 200 is transferred to the transfer card.

A speaker may be provided. An on / off operation and a display page update can be performed by a key operation (not shown) of the operation unit 17a. The electronic paper panel 17b is of a type that maintains the display even in the off state. In the ROM of the transfer card 17, a transfer card ID that is an identification code for identifying the transfer card 17 is written.

  In the present embodiment, the same information as that transmitted from the portable terminal 2 to the analysis center 200 is downloaded from the portable terminal 2 to the transfer card 17 at the environmental sample collection point 100. Instead of downloading the content information, the content information may be downloaded from the analysis center server 6 at the stage of an acceptance procedure in the analysis center 200 described later.

Instead of providing each button 81, 82, 83 on the operation unit 9b, the display unit 9a is used as a touch panel type display unit 9a, and an icon button is displayed on the display unit 9a by software installed in the terminal device 9, and the icon The buttons may serve as the buttons 81, 82, 83, etc.
A personal computer 8 is connected to the LAN 7 via a terminal device 9 as necessary. The personal computer 8 includes a display device, a keyboard, and a mouse as input / output devices.

(Acceptance procedure)
Below, the method of data collection in each booth 120 is demonstrated with a typical example.
For example, as shown in FIG. 7, in the booth 120 </ b> A, the measurement / analysis worker 18 </ b> B uses the personal computer 8 to perform an acceptance procedure for the environmental sample 13 </ b> A (leaf vegetable sample).
This work step corresponds to step S11 of the flowchart shown in FIG.

In the booth 120A, a terminal device 9A, a work table 113A, and a personal computer 8 connected to the terminal device 9A are installed. The personal computer 8 is loaded with a program for accepting procedures, accepts the ID information of the RFID tag 12A and the transfer card ID of the transfer card 17 transmitted from the terminal device 9A, and automatically stores them in the database 6a. The information stored in the database 6a when the environmental sample 13A is collected in the collection container 11A labeled with the ID information (hereinafter referred to as “collection information”) can be read and displayed on the display device. Then, an acceptance identification code is added to the accepted environmental sample 13A, and the subsequent record management in the analysis center 200 has a function of registering it so as to be arranged in accordance with the accepted sample identification code.
Note that the measurement / analysis worker 18B wears an employee card 19 containing an RFID tag 12P on his chest.

Hereinafter, a specific data collection method at the time of receiving work will be described.
The measurement / analysis worker 18B places the collection container 11A containing the environmental sample 13A and the transfer card 17 on which the worker 18A downloaded the collection time information on the work table 113A when the environmental sample 13A is collected.
The measurement / analysis operator 18B operates the reading button 82 of the operation unit 9b (see FIG. 8) to transfer the transfer card ID of the transfer card 17 to the terminal device 9A and the ID information of the RFID tag 12A attached to the collection container 11A. The ID information of the RFID tag 12P of the employee card 19 is read. The read transfer card ID and the ID information of each of the RFID tags 12A and 12P are temporarily stored in the memory 76 (see FIG. 8) and also transmitted to the personal computer 8 via the LAN communication unit 74.

The program for the acceptance procedure of the personal computer 8 reads the collection time information labeled with the ID information of the RFID tag 12A stored in the database 6a, and displays it on the display device.
The measurement / analysis operator 18B operates the transfer card 17 to check the contents displayed on the electronic paper panel 17b (see FIG. 8) and the contents displayed on the display device. If there is no mistake in both contents, the acceptance sample identification code is automatically generated in the acceptance procedure program by operating the keyboard or mouse, and the acceptance sample identification code, the ID information of the RFID tag 12A of the collection container 11A and the transfer are transferred. The transfer card ID of the card 17 is related, added as an additional label to the information at the time of collection, and registered as management history information (registration of an accepted sample identification code in the database 6a). At that time, the receiving procedure program sends a command to the control unit 71 of the terminal device 9A via the LAN communication unit 74, and also receives the received sample identification code as an additional label to the transfer card 17 and the ID of the RFID tag 12A of the collection container 11A. The relationship with the information is written (registration of the received sample identification code to the transfer card 17).
Subsequent record management in the analysis center 200 is performed in accordance with the received sample identification code in such a manner that record information in each work step is added to the registered management history information one after another.

  When the measurement / analysis operator 18B operates the record writing button 83 of the operation unit 9b, the registration acceptance work record is labeled with the received sample identification code described above, and the ID information and date / time information of each of the RFID tag 12P and the RFID tag 12A. Is written to the database 6a and downloaded to the transfer card 17.

  If a plurality of environmental samples 13A (in this example, the same reference numerals are used, but environmental samples 13B and 13C having different modes may be used) at individual sampling points, the individual collection containers 11A (here, the same are exemplary) If the samples are collected in the collection containers 11B and 11C having different shapes), the second and subsequent collection containers 11A are put on the work table 113A one by one, and new collection time information is downloaded. The transfer card 17 that is not present is placed on the work table 113A. Then, the read button 82 is operated again to obtain the transfer card ID of the transfer card 17 on the terminal device 9A, the ID information of the RFID tag 12 attached to the collection container 11, and the ID information of the RFID tag 12P of the employee card 19. Let me read. The read transfer card ID and the ID information of each of the RFID tags 12A and 12P are temporarily stored in the memory 76 (see FIG. 8) and also transmitted to the personal computer 8 via the LAN communication unit 74.

The program for the acceptance procedure of the personal computer 8 reads the collection time information labeled with the ID information of the RFID tag 12A stored in the database 6a, and displays it on the display device.
The measurement / analysis operator 18B operates the keyboard or mouse to automatically generate the acceptance sample identification code in the acceptance procedure program, and the acceptance sample identification code, the ID information of the RFID tag 12A of the collection container 11A, and the transfer card 17 transfer card IDs are associated with each other, added to the collection time information as an additional label, and registered as management history information (registration of an accepted sample identification code in the database 6a). At that time, the receiving procedure program sends a command to the control unit 71 of the terminal device 9A via the LAN communication unit 74, and also receives the received sample identification code as an additional label to the transfer card 17 and the ID of the RFID tag 12A of the collection container 11A. The relationship with the information is written (registration of the received sample identification code to the transfer card 17), and the collection time information stored in the database 6a is also written. The determination in the control unit 71 as to whether or not the collection time information is also written can be easily determined by whether or not the collection time information is written in the transfer card 17.

Then, when the measurement / analysis operator 18B operates the record write button 83 of the operation unit 9b, it is labeled with the received sample identification code as the registration acceptance work record, and the ID information of the RFID tag 12P and the RFID tag 12A, The date / time information is written in the database 6a and also downloaded to the transfer card 17.
As a result, even when a plurality of environmental samples 13A are collected at one sampling point, the management history information can be registered by assigning the received sample identification code to each individual container 11A, and management in the analysis center 200 thereafter. History information can be managed reliably.

In the above acceptance procedure, only the registration of the sample identification code has been exemplarily described, but actually, the purpose of measurement / analysis such as radiation measurement, specific hazardous substance measurement, etc. differs depending on the customer code or order code. Therefore, according to the customer code or order code recorded in the collection information, the measurement / analysis target table associated with the customer code or order code registered in advance in the database 6a is searched to determine the measurement / analysis target. Then, by recording in the management history information, the measurement / analysis object is also recorded on the transfer card 17, so that the measurement / analysis operator 18 </ b> B determines whether the measurement / analysis object displayed on the transfer card 17 Compared to using a transfer card with handwritten work instructions, as work steps such as processing and sample preparation can be performed. , It is possible to prevent a mistake such as transcription errors.
If necessary, the measurement / analysis operator 18B replaces data such as the location of the collection site and the environmental sample with character information and codes from the image information, audio information, GPS location information, etc. included in the collection time information. To do.

(Detailed work steps for pretreatment, sample preparation, measurement and analysis)
Next, a recording data collection method for each detailed work step at the stage of preprocessing, sample preparation, measurement / analysis using each processing apparatus 50 and the like will be described using typical examples.

When the timer 51b is started, an ON signal is transmitted from the high-temperature ashing device 50A to the terminal device 9B, received by the communication unit 73, and the control unit 71 temporarily stores the date and time of reception of the ON signal in the memory 76 as date information. This is displayed on the part 9a. When the set time of the timer 51b is reached, the high-temperature ashing device 50A stops energization, and an off signal is transmitted from the high-temperature ashing device 50A to the terminal device 9B. Thereafter, the power on / off switch 51a of the high-temperature ashing device 50A is turned off. The communication unit 73 receives the off signal, and the control unit 71 temporarily stores the date and time of the off signal reception in the memory 76 as the date and time information and displays it on the display unit 9a.

  The measurement / analysis operator 18B takes out the crucible and cools it, and then transfers the ashed sample to the container 44A. Then, the measurement / analysis operator 18B operates the recording / writing button 83 of the operation unit 9b. The control unit 71 searches the registered label in the database 6a using the ID information temporarily stored in the memory 76 to find the received sample identification code associated with the ID information, and records information under the label of the identification code.

At that time, the control unit 71 writes similar recording information to the transfer card 17.

Thus, even if the ashed sample is put in the container 44A, the container 44A is associated with the receiving sample identification code via the collection container 11A, and the consistent management is taken over.
Here, the container 11A corresponds to the first container of the present invention, and the container 44A corresponds to the second container.

The container 44B is set in the microwave decomposition apparatus 50C, the power on / off switch of the microwave decomposition apparatus 50C is turned on, and the timer is set to a predetermined time. When the timer is started, an ON signal is transmitted from the microwave decomposition apparatus 50C to the terminal device 9C, the communication unit 73 receives it, and the control unit 71 temporarily stores the date / time of reception of the ON signal in the memory 76 as date / time information and a display unit 9a is displayed. When the set time of the timer is reached, the microwave decomposing apparatus 50C stops its operation, and an off signal is transmitted from the microwave decomposing apparatus 50C to the terminal device 9C. Thereafter, the power on / off switch of the microwave decomposition apparatus 50C is turned off. The communication unit 73 receives the off signal, and the control unit 71 temporarily stores the date and time of the off signal reception in the memory 76 as the date and time information and displays it on the display unit 9a.

  The measurement / analysis worker 18B takes out the container 44. Then, the measurement / analysis operator 18B operates the recording / writing button 83 of the operation unit 9b. The control unit 71 searches the registered label in the database 6a using the ID information temporarily stored in the memory 76 to find the received sample identification code associated with the ID information, and records information under the label of the identification code. As (sample processing information), correspondence between ID information of the RFID tags 12B, 12C, and 12D of the container 44A, the container 44B, and the container 45A, an identification code of the microwave decomposition apparatus 50C, date / time information at the time of on / off, measurement / analysis work The ID information of the RFID tag 12P of the person 18B is written in the database 6a. At that time, the control unit 71 writes similar recording information to the transfer card 17.

Thus, even if the sample is transferred to the container 44B, the container 44B is associated with the received sample identification code via the collection container 44A, and the consistent management is taken over.
Here, the container 44A corresponds to the first container of the present invention, and the container 44B corresponds to the second container.

(Radiation measurement)
The next example corresponds to step S26 in the flowchart of FIG.
A terminal device 9E and an α-ray measuring device 50E are installed in the booth 120E. In the booth 120E, the measurement / analysis worker 18B performs the work of measuring / analyzing the prepared measurement sample 15 with the α-ray measurement device 50E.

When the α-ray measuring device 50E is activated, an ON signal is transmitted from the α-ray measuring device 50E to the terminal device 9, received by the communication unit 73, and the control unit 71 temporarily stores the date and time of receiving the ON signal in the memory 76 as date / time information. And displayed on the display unit 9a. When the measurement and analysis of the α-ray measuring device 50E are completed, the off-signal and the measurement / analysis result information are transmitted from the α-ray measuring device 50E to the terminal device 9E. The communication unit 73 receives the off signal and the measurement / analysis result information, and the control unit 71 temporarily stores the date / time of the off signal reception as date / time information in the memory 76 in addition to the measurement / analysis result information (measurement result information). Displayed on the display unit 9a.

  The measurement / analysis worker 18B takes out the container 43. Then, the measurement / analysis operator 18B operates the recording / writing button 83 of the operation unit 9b.

(Example of detailed work flow of sample pretreatment, sample preparation, measurement and analysis in the analysis center)
FIG. 9 is a flowchart showing an example of a detailed work flow of sample pretreatment, sample preparation, measurement / analysis in the analysis center after receiving an environmental sample (leaf vegetable sample). These work procedures are changed according to the state of the sample, and are determined by standards and the like.
When the environmental sample 13A (see FIG. 7) is received in the analysis center 200 (step S11), the weight of the sample 13A is first measured (step S12). Thereafter, it is dried in a microwave oven (step S13), and then incinerated with the high-temperature ashing apparatus 50A (see FIG. 7) (step S14). A mixed solution of hydrogen nitrate and nitrate is added to the ashed sample, and the sample is decomposed by the microwave decomposition apparatus 50C (see FIG. 7) (step S15). Next, a sodium nitrite solution is added, stirred and heated (step S16). Thereafter, suction filtration is performed with a membrane filter (step S17). Steps S12 to S17 are the first stage pretreatment for obtaining the sample solution for analysis, and the filtrate obtained in step S17 is the sample solution for analysis.

  Trivalent iron hydroxide (iron (III) hydroxide) is added to the sample solution (step S18), and further, sodium hydroxide is added, stirred, heated, and then centrifuged (step S19). Hydrochloric acid / ammonia water is added to the resulting precipitate to form a hydroxide precipitate (step S20). Ammonia water is added to the produced hydroxide precipitate, heated and boiled, and then centrifuged again (step S21). The precipitate is dissolved with nitric acid or the like to obtain a resin column separation solution (step S22). Steps S18 to S22 are the second stage pre-processing for collecting the α-destroying substances.

The resin column separation solution is passed through the resin column (column separation) (step S23). An eluent is allowed to flow through the resin column to elute the α-destroying substance (elution of the α-destroying substance with the eluent) (step S24). Steps S23 and S24 are the third stage pre-processing of separation using a resin column. In step S25, in order to prepare a measurement sample so that the α-disintegrating substance can be quantified, the solution eluted in step S24 is evaporated to dryness and collected on a filter paper (evaporated dry matter is collected on the filter paper). (Step S25). The form of the evaporated and dried product placed on the filter paper is the α-ray measurement sample 15 (see FIG. 7).
In step S26, α rays are measured by an α ray measuring apparatus 50E (see FIG. 7) using a semiconductor detector. In the operation of step S26, the α-ray measuring device 50E can measure the energy and intensity of the α-ray, identify the nuclide that emits the α-ray, and quantify the amount.
Note that the work records from step S11 to step S26 are accumulated in the database 6a for each environmental sample 13A collected and received by each booth 120 (terminal device 9 in FIG. 7) as described above. .

  In step S27, the measurement / analysis result is analyzed and reported. For example, the worker 18B uses the personal computer 8 in the booth 120F to evaluate the amount of radionuclide contained in the unit weight at the time of collection of the environmental sample 13A, evaluate the reference value, and form electronic information. And submit it to the database 6a.

In step S28, the worker 18C (see FIG. 7) receives the report submitted at the booth 120G, the information at the time of sampling, and the recording information from the reception of the sample 13A in the analysis center 200 to the creation of the report. An inspection is performed using the computer 8 to check whether there is any error or abnormality (analysis work quality check). If there is no abnormality, the management history information is closed. Here, the “close process” is a process for setting a write prohibition flag by adding the ID information of the RFID tag 12P of the worker 18C who is the checker so that the record cannot be added or changed any more.
In step S <b> 29, the worker 18 </ b> C transmits the evaluation result of the report that has passed the quality check of the analysis work to the central server 1 of the overall management center 300.
Finally, the operator 18C erases the data recorded on the transfer card 17 (see FIG. 7) (deletion of electronic paper data, step S30). The transfer card 17 is reused.

As described above, according to the present embodiment, details of collection of information at the time of collection at the environmental sample collection point 100 to the analysis center server 6, acceptance of environmental samples at the analysis center 200, preprocessing, sample preparation, measurement / analysis are detailed. By using the portable terminal 2 or the terminal device 9 (9A to 9E), data collection to the analysis center server 6 of recorded information (sample processing information) and measurement / analysis result information (measurement result information) in a simple work step is performed. Conventionally, as shown in FIG. 10 (a), the container is identified with a memo sticker, and the measurement / analysis operator 18B who has performed pre-processing, sample preparation, measurement / analysis and the like manually writes the information one by one and records the final record. As shown in FIG. 10B, it is possible to substantially eliminate the hassle of manually inputting a handwritten record and measurement result information.
Since the transfer card 17 is in the form of electronic paper, it can also eliminate the hassle of handwriting input, and since the transfer card 17 is handled together with the sample container, the progress of the work can be easily checked and entered. Leakage can also be prevented.
Further, communication between the terminal device 9 and the RFID tag 12, the transfer card 17, or the processing device 50 is performed in each work step because it is performed in each booth 120 partitioned by the partition 111 having an electromagnetic wave shielding function. The ID information of the RFID tag affixed to other containers is not read.

Further, the information at the time of collection, the record information, and the measurement / analysis result information are stored in the database 6a of the analysis center server 6 in a consistent manner with the ID information of the RFID tag attached to the collection container 11A. Therefore, the recorded information and measurement / analysis result information generated in the analysis center 200 can be easily searched, and there is a point that seems to be strange in the measurement / analysis result. It is possible to easily trace the contents of the preprocessing, the identification of the measurement / analysis worker 18B who performed the preprocessing and sample preparation, and the like.
As a result, even if pre-processing and sample preparation are performed by a plurality of measurement / analysis workers 18B, it is possible to prevent description errors that are likely to occur when handwritten entry of recorded information and measurement / analysis result information is performed.

  In particular, since recorded information and analysis / result information are accumulated in the transfer card 17 via the terminal device 9 and the contents thereof can be displayed on the display unit 17b for confirmation, there is a writing error as in the case of a handwritten transfer card. Can be prevented.

(Modification)
(1) In the above-described embodiment, the collection container 11A, the containers 44A and 44B (see FIG. 7) used for pretreatment, and the RFID tag 12 attached to the container 43 (in FIG. 7, 12A, 12B, 12C, 12M) is a read-only type but a writable type. In step S11, an acceptance sample identification code with a predetermined identification code is written in the RFID tag 12A of the collection container 11A, and the subsequent booths 120B, 120C, etc. For each processing operation step, the received sample identification code may be written into the RFID tag 12 on which the received sample identification code with the predetermined identification code is recorded by the terminal device 9.
By writing the received sample identification code in the RFID tags 12A, 12B, 12C, and 12M in this way, after pre-processing or sample preparation without checking the recorded information related to each received sample identification code stored in the database 6a The receiving sample identification code can be taken over by the RFID tag 12 of the container into which the sample is subsequently placed.

(2) In the above embodiment, the terminal device 9 is provided with the on / off button, the read button, and the record / write button, but the present invention is not limited to this. If the RFID tag 12 enters the radio wave coverage of the RFID tag R / W, the RFID tag 12 is recognized, ID information is read, processing information from the processing device 50 is received, and the RFID tag 12 receives the radio wave coverage of the RFID tag R / W. It may be detected that the recording information is lost and the recording information is written to the database 6a.

(3) When the sample container and the transfer card 17 are misplaced in the embodiment, there is a discrepancy between the ID information of the RFID tag 12 of the container and the ID information of the RFID tag 12 of the container recorded on the transfer card 17.
