【摘要】 根据长江水系放射性水平调查结果,按照不同照射途径估算了不同子区居民个体因使用长江水而导致的个人剂量,并估算了整个长江流域居民的集体剂量.偏保守的计算结果表明,因使用长江水所致,集体剂量约为1.46×103人-Sv/a,最大个人剂量为8.5×10-5(Sv/a,约为天然本底辐射水平的3.5%.更多还原

【Abstract】 Individual dose to public resided in different sub-region of Yangtze valley and collective dose for the whole of Yangtze valley are estimated according to various irradiation pathways on the basis of the results of investigating the radioactive level on Yangtze River system. From the conservative calculated results, it is shown that the collective dose is about 1.46×103 man－Sv/a as well as the greatest individual dose is only 8.5×10－5 Sv/a and is about 3.5% of natural background radiation.更多还原
