摘要
对丹东地区的地表γ射线进行测量。使用BH3103A便携式X-γ剂量率仪,采用网格式测量方法对全地区地表γ射线的剂量率进行了测量,查清了丹东地区地表γ射线水平:丹东地区地表γ射线平均水平8.48×10-8Gyh-1,远高于辽宁省的平均水平,其中凤城境内的17.83×10-8Gyh-1监测值为辽宁省的最大值。
In recent years,DPRK has carried on two nuclear tests,causes Dandong area the environment radiation pressure to increase suddenly in addition,China plans to establish a new nuclear power station in Dandong,Therefore,it is necessary to carry on the survey to Dandong environmental terrestrial gamma-radiation dose rate and to find out its radioactive background condition.The gamma radiation background situation has been obtained by using grid method with the portable X-γ dose rate instrument.The averaged gamma dose rate of Dandong is 8.48×10-8Gyh-1,higer than that of Liaoning region,and Fengcheng＇s is maximan one.
