摘要
基于2018-2020年数据,比较了3个实验室辐射检测能力水平。比对的指标有γ辐射剂量率、α、β表面污染水平、工频电场强度、工频磁感应强度和电场强度(射频)。比对结果表明,三家实验室辐射检测能力均表现较大的年际变异。2018年,三家实验室的工频磁感应强度检测不满意,2018-2019年,工频电场强度检测无法评价,其余指标均取得满意成绩。查找原因更换设备后,2020年所有测量指标比对均取得满意结果,三家实验室辐射检测能力差异不明显。
The radiationdetectioncapability of three laboratories was compared according to data obtained from 2018 to 2020.The major index selected for a comparison wereγradiation dose rate,αandβsurfacecontaminationlevel,power frequency electric field intensity,power frequency magnetic induction intensityand electric field intensity(RF).It was found that their radiation detection ability were all time-dependent.In 2018,the three laboratories investigated were all weak in detecting power frequency magnetic induction intensity.From 2018 to 2019,the power frequency electric field intensity detection cannot be evaluated.By taking action to replace the equipment after a fault diagnosis,the problems were solved,and all the laboratories showed no obvious differences in radiationdetectioncapability.
