反场箍缩聚变实验装置辐射防护监测分析

Radiation Protection Monitoring and Analysis of the Reversed Field Pinch Experimental Device

本文介绍了我国反场箍缩聚变实验装置辐射种类及水平,估算单次放电对10 m处人员导致的辐射剂量约为0.025μSv,估算全年正常放电导致工作人员剂量最大为2.5 mSv。同时,分别委托两家辐射监测单位独立进行光子、中子辐射累积剂量检测,对比分析测量结果可见,该装置在现运行条件下所产生的辐射剂量对周围环境和公众影响较小。提出了辐射安全管理与防护监测方面的若干建议。

This article introduces the radiation type and level of the reversed field pinch experimental device in China.It analyses the radiation type of this RFP and estimates the dose for a signal discharge is about 0.025 μSv.According to this estimate,the annual dose of radiation workers for will be 2.5 mSv. Cumulative dose of photon and neutron monitoring is carried out independently by two units,and the result shows under the current operating conditions the radiation dose produced by the device has little impact on the surrounding environment and the public.Some suggestions on radiation safety management and monitoring are also put forward.
