摘　　要：介绍了安仁石煤发电厂周围环境放射性水平调查的方法与结果。结果表明：电厂周围环境γ辐射剂量率水平，环境土壤和下游农田土壤中２３８Ｕ、２２６ Ｒａ 含量，环境大气中２３８ Ｕ、２３２Ｔｈ、２２６ Ｒａ、４０ Ｋ、２２２Ｒｎ 浓度及α潜能值，排出水中天然铀和钍的浓度等均比对照点有升高；居住在碳化砖房内的居民，其年附加有效剂量当量为２．７ ｍThe radioactivity level of the ambient environment of Anren Bone coal Fueled Power Station is introduced in the paper. The γ radiation dose rate in the environment, the content of 238 U and 226 Ra in the ambient soil and the farmland downwind, the concentrations of 238 U , 232 Th, 226 Ra, 40 K and 222 Rn aswell as α potential energy in air, and the concentrations of natural U and Th in effluent are higher than on the contrast points. The additional annual effective dose equivalent to the residents living in the house made of cinder bricks is 2.7 mSv.
