2015年,辐射安全研究所对用于放射性工作人员内照射监测的全身计数器进行了改造,改造主要内容之一是全身计数器低本底屏蔽室的通风降氡系统,其作用是降低屏蔽室内的氡浓度,减小氡及其子体对本底的贡献,提高全身计数器测量的灵敏度。全身计数器屏蔽室位于半地下,屏蔽层由外
In 2015, the Institute of Radiation Safety carried out a revamping of the whole-body counter for internal radiation monitoring of radioactive workers. One of the main contents of the revamp is the ventilation and radon lowering system of the low-risk shielded room with a full-body counter. Its function is to reduce radon in the shielded room Concentration, reduce the contribution of radon and its daughters to the background, and improve the sensitivity of the whole body counter measurement. Whole body counter shielded room is located in the semi-underground, shielding from the outside
