| 摘 要： | 安徽石台大山地区分布着较为广泛的下寒武统荷塘组石煤层,而石煤出露地区即是富硒区也是放射性水平含量较高区。根据本次调查在下寒武统荷塘组含煤岩系分布区的地方,其天然γ射线水平较高,不适宜人类在此居住。而调查区内的居民村庄大多远离含煤岩系分布区的地方,对当地的居民接收天然γ辐射照射人均年有效剂量估算,该地区居民居住的村庄和学校的人年均天然贯穿辐射有效剂量当量为0.32~0.43 m Sv。因此,可以确定认为该地区居民居住γ射线辐射水平对人居环境影响不大,天然γ射线辐射环境对当地居民健康是安全的。

| Abstract: | tone coal beds occurred in Lower Cambrian Hetang Formation are widely distributed in Dashan,Shitai county,Anhui province,but the areas where stone coals are exposed are also Se-rich districts with high radiation levels.The present radioactivity investigation indicates that the localities with distribution of coal-bearing strata of Lower Cambrian Hetang Formation show high natural γ-ray radiation levels and are unfit for human residence.However,the most residential villages in the investigation area are far from those localities.By estimating natural γ radiation annual effective dose per capita received by local residents,it is found that the natural radiation effective dose equivalent per capita for the residents of local villages,schools and electric power stations is about 0.32-0.43mSv per capita.Therefore,it is determined that the γ-ray radiation level has little effect on the human′s living environment and the natural γ-ray radiation environment is safe to the health of local residents. |
