摘要
由于相继建设广东大亚湾核电站 (GNPS)和岭澳核电站 (LAPS) ,大亚湾地区自 1 988年至 2 0 0 0年先后进行了三次环境 γ辐射剂量率调查。比较分析三次测量结果 ,大亚湾地区原野和室内的 γ辐射水平总体上保持不变 ,道路的 γ辐射水平则略有上升。本文还分析了不同时间特定区域 γ辐射水平调查结果差异的原因 ,说明在环境 γ辐射剂量率测量中 。
Investigations were carried out of radiation level around Daya Bay for three times since the construction and operation Daya Bay Nuclear Power Station and Lingao Nuclear Power Station in Guangdong province in the period of 1988 to 2000. As shown by the investigation, the radiation levels both in the field and indoors remains unchanged by and large but slightly higher than before on the roads. Also this paper gives the analysis of variations in radiation levels form site to site and from time to time. It was shown that, for environmental γ radiation level measurements, typical measuring sites have significant impact on the meaning results.
