The expert group listened to the work report of the project team, reviewed the relevant technical data, and watched a live demonstration. After questioning and discussion, the expert group unanimously believed that the submitted acceptance data was complete, complete and standardized, and met the project acceptance requirements. The project met the national metrological verification. The requirements of the test methods, technical requirements, test equipment and environmental conditions of the procedures, and the source and expenditure of the project funds are standardized and reasonable, and they agree to pass the acceptance check.

Nuclear power meters are closely related to safety protection, health care and environmental monitoring. It is of great importance to ensure the accuracy of their values. If the amount is inaccurate, personal dose assessment and radiation safety supervision will be seriously affected, which may lead to nuclear accidents, threaten the health and safety of workers and even the nearby residents, and cause major public safety incidents. However, the current domestic calibration of ionizing radiation protection devices, dosimeters, and other nuclear power meters has not been able to fully develop, especially in Shandong Province, this area is blank and cannot fully meet various energy ranges and dose rate ranges. The instrument inspection and calibration work, the nuclear power meter detection capability needs to be improved, and the value transfer and traceability system needs to be improved.

The completed SEPA science and technology project “Research on nuclear power meter detection device and research on traceable traceability system” established three sets of ionizing radiation dosimetry standards, and achieved different dose rates through different specifications of attenuators and precise distance adjustment positioning. The complete coverage of nuclear power meters is of great significance for the measurement of environmental monitoring, radiation protection, and treatment levels, as well as the transmission of measured values ​​and the traceability of measurement values.
