摘要
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。
This paper reports absorbed dose rate in air for natural radiation and concentration radionuclides for food.The annual effective dose equivalents for inhabitant produed external irradiation is 0.85mSv,the contributions of cosmic-ary. K-40、 U-238 decay series and Th-232 decay series are 0.25, 0.19. 0.12 and 0.29mSv respectively. that produed internal irradiation is 1.5mSv,thecontribution of K-40, U-238 decay series and Th-232 decay series are 0.18. 1.26 and 0.009mSv respectively.the total annual effective dose equivalent is 2.3mSv,inside,cosmic-ary,K-40,U-238 series and Th-232 series are 0.25. 0.37, 1.38 and 0.30mSv respectively.As a resrlt,the natural radiation in Anhui areais noumal background level similar UNSCEAR report (1988)
