Thermoluminescent dosemeter dynamic distribution system and method

Abstract

The invention relates to a thermoluminescent dosemeter dynamic distribution system and method. The dynamic distribution system comprises a thermoluminescent dosemeter storage box, a primary database, a backup database, a human-computer interaction display terminal, a scanner, a printer, a card reader and a thermoluminescent dosemeter card. The human-computer interaction display terminal is connected with the scanner, the printer, the card reader and an intermediate network. The primary database is connected with the intermediate network and used for saving work card information uploaded by the human-computer interaction display terminal, information of the thermoluminescent dosemeter card and information of the thermoluminescent dosemeter storage box. The backup database is connected with the intermediate network and used for saving the data of the primary database. According to the dynamic distribution system and method, the distribution number of the thermoluminescent dosemeter can be greatly reduced, personal dose monitoring cost can be reduced, the intermediate links of original fixed distribution can also be reduced, and monitoring effectiveness, reliability and management efficiency can be enhanced.

Description

technical field [0001] The invention relates to the technical field of personal dose monitoring, and more specifically relates to a dynamic dispensing system and method for thermoluminescent dosimeters. Background technique [0002] Thermoluminescent personal dosimeters are used in nuclear facilities (nuclear power plants) occupational radioactive personal dose monitoring. In order to achieve effective monitoring of occupational radioactive personal doses in operating units, each radioactive worker is equipped with a fixed thermoluminescent dosimeter (also It is called TLD), which originally adopts the centralized management method of substations, that is, it is stored centrally at the entrance of the control area of ​​each power station, and all personnel who need to enter the control area are assigned a fixed TLD at the centralized storage point. This management method shows many disadvantages, mainly as follows: [0003] 1. Each radiation worker is equipped with a set of...

AI Technical Summary

Problems solved by technology

The required TLD resources are huge

[0004] 2. According to the fixed TLD distribution mode per person, each power station needs to install at least 8 TLD storage boxes on-site instrument room, and with the increase of personnel, the need continues to increase, and the on-site space is becoming increasingly insufficient

[0005] 3. With the sharp increase in the number of trainees and the mobility of trainees in foreign bases, the subsequent workload of distribution and recycling is increasing, which is a serious waste of resources and time-consuming Recycle TLD again)

[0006] 4. With the commissioning of the new power station, if the TLD distribution management is carried out in the above way, the demand for TLD will increase by at least 50%, and the accompanying distribution and measurement workload will also increase sharply

[0007] 5. Each person and each power station need to be assigned a fixed TLD card. No matter whether the wearer needs to enter the control area to work during the monitoring period, it needs to be distributed, measured and read. The workload is very huge and there is a considerable workload It is wasteful, that is, some personnel who have been issued with TLD did not enter the control area, and there is no need to test and read the TLD at all, that is, the actual utilization rate of TLD is low

[0008] 6. When new employees arrive at the scene and need to carry out dose monitoring, it is necessary to apply, and the dose management personnel will carry out technical processing and numbering of the TLD before distributing it to the on-site TLD storage place for use when entering the control area. The work efficiency is very low, and It is easy to cause human distribution errors

Therefore, a lot of labor costs have been paid in the process of personnel onboarding and resignation
