两批LiF(Mg、Cu、P)剂量计在环境中测量结果的差异与原因分析

ANALYSIS OF DIFFERENCES OF ENVIRONMENTAL MONITORING RESULTS BETWEEN TWO BATCHES OF LiF(Mg,Cu,P) DOSIMETERS

两批LiF(Mg、Cu、P)热释光剂量计对大亚湾核电站环境监测的结果产生了15%的差异。本文实验分析了差异产生的原因,发现并验证这种差异是由于它们对宇宙射线的响应和自身本底的差别而造成的。

The difference of environmental monitoring results of two batches of LiF（ Mg, Cu, P）glass pipe dosimeters in Daya Bay Nuclear Power Station is 15%. Through cosmic ray experiments, it was discovered that the cause is two batches of thermoluminescence dosimeters （TLD） have different response to cosmic rays and TLD＇ s itself background.
