  The entry display device 13 displays information that the operator should know when entering. The information that should be known before entering varies depending on the job title or work content of the worker. For example, the person in charge of work needs to know the name of each worker in the work team he / she manages, the accumulated dose, and the like. For example, a general worker needs to know the name of the person in charge of the work team to which he belongs, his own accumulated dose, his work contents, and the like. The entrance display device 13 is composed of, for example, a liquid crystal display and / or a speaker, and notifies the operator of such information by, for example, a text message, a still image, or a moving image sound.

  FIG. 8 is a schematic diagram illustrating an example of the display of the entrance display device 13.

The That is, the name 202 of the worker whose cumulative dose 204 is equal to or greater than a predetermined ratio of the planned dose 212, the cumulative dose 204, and the planned dose 212 are displayed in the notification area 1002. Thereby, the person in charge of the work can know that in the work concerned, it is necessary to pay sufficient attention to the accumulated doses 204 of these workers.

  FIG. 10 is a schematic diagram illustrating another example of information displayed in the notification area of the entrance display device 13. The information shown in FIG. 10 is notified when, for example, the accumulated dose 204 of the inbound person is equal to or higher than a predetermined ratio of the planned dose 212. In other words, the accumulated dose 204 and the planned dose 212 of the person in charge are displayed in the notification area 1002. Thereby, the worker who enters the area can know that he / she has to be careful about his / her accumulated dose 204.

  FIG. 11 is a schematic diagram illustrating an example of the body surface monitor 14. The body surface monitor 14 is a retreat gate for checking a worker's retreat and monitoring body surface contamination, and includes a retreat reader 15 and a retreat display device 16.

  The withdrawal area reading device 15 reads the worker ID 201 from the ID card C and the exposure dose from the personal exposure dosimeter D, and transmits it to the server 10. The withdrawal area reading device 15 reads the worker ID 201 and exposure dose data from the ID card C and the individual exposure dosimeter D, for example, by non-contact communication.

  The withdrawal display device 16 displays information that the operator should know for future work. Information to be known for future work varies depending on the exposure dose in the work or the knowledge level 206 regarding the radiation protection of the worker. For example, when the exposure dose in the work is higher than a predetermined value, or when the accumulated dose 204 after the work is a predetermined ratio or more of the planned dose 212, the worker needs to know that fact. Further, in order to ensure the safety of work, the worker must maintain and improve the knowledge level 206 regarding radiation protection. The entrance area display device 13 is composed of, for example, a liquid crystal display and / or a speaker, and notifies the operator of this information with video and / or audio.

  FIG. 12 is a display example showing an example of the display of the withdrawal display device 16. For example, in the area 1101 of the withdrawal display device 16, the name 202 of the person leaving the area, the withdrawal time, the work subject 211, the planned dose 212, the accumulated dose 204, and the like are displayed. For example, the notification area 1102 displays information that should be known when leaving. In FIG. 12, information of the general knowledge information 104e shown in FIG. 6 is displayed. Returning to the description of FIG.

  The controller 27 controls the server 10 and each DB 28-30. The controller 27 manages the entry / exit of the worker. That is, when the controller 27 receives the worker ID 201 from the entry gate 11, the controller 27 registers in the personal information DB 28 that the worker associated with the worker ID 201 has entered.

  When the controller 27 receives the worker ID 201 and the exposure dose from the body surface monitor 14, the controller 27 registers in the personal information DB 28 that the worker related to the worker ID 201 has left, and adds the exposure dose to the integrated dose 204. To do.

  When the controller 27 receives a request for the personal information 101 corresponding to the worker ID 201 from the entrance gate 11 or the body surface monitor 14, the controller 27 acquires the personal information 101 corresponding to the worker ID 201 from the personal information DB 28. It returns to the gate 11 or the body surface monitor 14.

  When the controller 27 receives a request for the work information 102 corresponding to the work ID 205 from the entry gate 11 or the body surface monitor 14, the controller 27 acquires the work information 102 corresponding to the work ID 205 from the work information DB 29. Or it returns to the body surface monitor 14.

  Upon receiving the request for the specific knowledge information 103 and / or the general knowledge information 104 from the entrance gate 11 or the body surface monitor 14, the controller 27 acquires the specific knowledge information 103 and / or the general knowledge information 104 from the knowledge information DB 30, It returns to the entrance gate 11 or the body surface monitor 14.

  At this time, the controller 27 may receive the work ID 205 from the entry gate 11 and return only the specific knowledge information 103 that is suitable based on the work environment 213 corresponding to the work ID 205. Alternatively, the controller 27 may receive the worker ID 201 from the retreat gate and return only the general knowledge information 104 having the difficulty level 233 that matches the knowledge level 206 of the worker.

  The management terminal 41 is a terminal for operating and managing the server 10 via the communication network 40. The management terminal 41 may operate and manage the entrance gate 11 and the body surface monitor 14 via the communication network 40.

  FIG. 13 is a flowchart showing an example of processing in the entrance gate 11. The entry gate 11 reads the worker ID 201 of the entry worker via the entry reading device 12 (S101). The entrance gate 11 acquires the personal information 101 corresponding to the worker ID 201 from the server 10 (S102). The entrance gate 11 refers to the post 203 of the personal information 101 and determines whether or not the worker is a “work manager” (S103). First, a case where the worker is a “worker” (S103: YES) will be described.

  The entrance gate 11 acquires the personal information 101 of each worker belonging to the work group managed by the person in charge of the work from the server 10 (S104). The entrance gate 11 compares the accumulated dose 204 of each worker belonging to the work team with the planned dose 212 related to the work, and the accumulated dose 204 is close to the planned dose 212 (that is, the accumulated dose 204 is the planned dose). It is determined whether or not there is an operator (at a predetermined rate or more of the dose 212) (S105).

  When there is a person whose accumulated dose 204 is close to the planned dose 212 (S105: YES), the entrance gate 11 displays the personal information 101 of the worker who is approaching the planned dose 212 as the entrance display device 13. (S106), and the process ends.

  When there is no person whose accumulated dose 204 is close to the planned dose 212 (S105: NO), the entrance gate 11 proceeds to the process of step S107.

  Next, a case where the worker is not the “work manager” (S103: NO), or a case where there is no person whose accumulated dose 204 approaches the planned dose 212 in step S105 (S105: NO) will be described. . The entrance gate 11 determines whether or not the operator's own accumulated dose 204 is close to the planned dose 212 (S107).

  When the operator's own accumulated dose 204 is approaching the planned dose 212 (S107: YES), the entrance gate 11 displays an entry indicating that the operator's own accumulated dose 204 is approaching the planned dose 212. The information is displayed on the device 13 (S108), and the process is terminated.

  When the operator's own integrated dose 204 is not close to the planned dose 212 (S107: NO), the entrance gate 11 receives from the server 10 the specific knowledge information 103 corresponding to the work ID 205 and the knowledge level of the worker. General knowledge information 104 conforming to 206 is acquired (S109).

  The entrance gate 11 calculates the display priority of the specific knowledge information 103 and the general knowledge information 104 (S110). Here, basically, the specific knowledge information 103 has a higher priority than the general knowledge information 104. However, the priority may be calculated by randomly weighting the specific knowledge information 103 and the general knowledge information 104 so that the same information is not displayed every time.

  The entrance gate 11 displays the specific knowledge information 103 or the general knowledge information 104 having the highest calculated display priority on the entrance display device 13 (S111), and ends the processing.

  FIG. 14 is a flowchart showing an example of processing in the body surface monitor 14. The body surface monitor 14 starts monitoring the contamination of the body surface (S201). And the body surface monitor 14 performs the process shown below during monitoring. The body surface monitor 14 reads the worker ID 201 and the exposure dose via the withdrawal area reading device 15 (S202). The body surface monitor 14 transmits the read worker ID 201 and exposure dose to the server 10, and acquires personal information 101 and work information 102 from the server 10 (S203). The exposure dose is added to the integrated dose 204 included in the personal information 101 acquired at this time. The body surface monitor 14 determines whether or not the operator's accumulated dose 204 is close to the planned dose 212 (S204).

  When the operator's integrated dose 204 is not close to the planned dose 212 (S204: NO), the body surface sensor proceeds to the process of step S207.

  When the operator's accumulated dose 204 is approaching the planned dose 212 (S204: YES), the body surface monitor 14 displays on the withdrawal display device 16 that the accumulated dose 204 is approaching the planned dose 212. (S205). And the body surface monitor 14 complete | finishes the said process, when monitoring is completed (S206: YES). On the other hand, when monitoring is not completed (S207: NO), the body surface monitor 14 progresses to the process of step S207.

  In step S207, the body surface monitor 14 acquires a plurality of general knowledge information 104 that matches the operator's knowledge level 206 from the server 10 (S207). For example, the general knowledge information 104 having the difficulty level 233 of the worker knowledge level 206 or higher is acquired from the server 10. The body surface monitor 14 displays one randomly selected from the plurality of general knowledge information 104 on the withdrawal display device 16 (S208). Then, the body surface monitor 14 determines whether or not the monitoring is completed (S209).

  When the monitoring is not completed (S209: NO), the body surface monitor 14 returns to step S208, selects another general knowledge information 104 at random, and displays it on the withdrawal display device 16. That is, the body surface monitor 14 switches the general knowledge information 104 one after another and displays it on the withdrawal display device 16 until the monitoring is completed.

  When the monitoring is completed (S209: YES), the body surface monitor 14 requests the server 10 to update (that is, level up or down) the worker's knowledge level 206 (S210), and ends the process. .

According to the present embodiment, for example, the following effects can be obtained.
1) The person in charge of work can know that there is an operator whose accumulated dose 204 is close to the planned dose 212 when entering the area. Thereby, the safety | security regarding an operator's exposure dose can be improved more.
2) When entering, the worker can obtain knowledge that is desirable to know in the work. Thereby, the safety | security regarding the said operator's said operation | work can be improved more.
3) Workers can confirm and acquire knowledge about radiation protection during retirement monitoring. As a result, maintenance and improvement of the worker's knowledge regarding radiation protection can be achieved.

  The above-described embodiments of the present invention are examples for explaining the present invention, and are not intended to limit the scope of the present invention to these embodiments. Those skilled in the art can implement the present invention in various other modes without departing from the gist of the present invention.

  For example, a part or all of the entrance gate 11 process shown in FIG. 13 and the body surface monitor 14 process shown in FIG. 14 may be executed on the server 10 side.

  For example, the display of the general knowledge information 104 at the time of withdrawal is made into a question format so that the worker can answer it. If the answer is correct, the knowledge level 206 of the worker is raised, and if the answer is incorrect, the knowledge of the worker The level 206 may be lowered.
