报导安徽省天然辐射的空气吸收剂量率和饮食中天然放射性核素的浓度。外照射对安徽居民产生的年有效剂量当量是０．８５ｍＳｖ，其中宇宙射线、Ｋ—４０，铀系和钍系的贡献分别为０．２５、０．１９、０．１２和０．２９ｍＳｖ；内照射为１．５ｍＳｖ，其中Ｋ—４０，铀系和钍系的贡献分别为０．１８、１．２６和０．００９ｍＳｖ。总的年有效剂量当量为２．３ｍＳｖ，其中宇宙射线、Ｋ—４０、铀系和钍系分别为０．２５、０．３７、１．３８和０．３０ｍＳｖ。与ＵＮＳＣＥＡＲ报告书（１９８８）的结果比较，安徽省的天然辐射属于正常的本底水平。
Reported the natural radiation in Anhui Province, the dose rate of air absorption and dietary natural radionuclide concentration. The annual effective dose equivalent of external exposure to Anhui residents is 0.85mSv, of which contribution to cosmic rays, K-40, uranium and thorium are 0.25, 0.19, 0.12 and 0.29 mSv, respectively; The irradiation was 1.5 mSv, of which K-40, uranium and thorium contributed 0.18, 1.26 and 0.009 mSv, respectively. The total annual effective dose equivalent is 2.3 mSv, of which cosmic rays, K-40, uranium and thorium are 0.25, 0.37, 1.38 and 0.30 mSv, respectively. Compared with the results of the UNSCEAR Report (1988), natural radiation in Anhui Province is at a normal background level.
