摘　　要：本文介绍2010~2014年用热释光剂量计测量广东省11个地市辐射环境质量的监测结果,结果表明:广东省11个地市热释光剂量计测得的空气吸收剂量率年均值范围为53.5~173.9 nGy/h,均值为118.5 nGy/h,最高值在珠海,最低值在湛江,与广东省环境天然辐射水平本底调查结果一致。监测点5年均值相对偏差最大为5.1%,热释光剂量计监测值与该点的瞬时测量值吻合度非常好,相对偏差最大为8.4%,说明监测点环境无变化且热释光剂量计监测数据稳定可靠。This paper introduces the monitoring results of radiation environmental quality measured by thermoluminescence dosimeter in 11 cities of Guangdong Province from 2010 to 2014.The results show that the highest annual average radiation level is 173.6±2.5 nGy/h in Zhuhai,and the lowest is 53.6±0.5 nGy/h in Zhanjiang.The radiation levels of 11 monitoring points are consistent with the historical survey results;Qingyuan City has the largest relative deviation of the five-year mean value of 11 measuring points,which is 5.1%.The thermoluminescence monitoring value is in good agreement with the instantaneous measurement value,and the maximum relative deviation is 8.4%only,indicating that the environment of the monitoring point remains the same as before,and the thermoluminescence monitoring data keeps stable and reliable.
