摘要
本文概述了我国天然辐射本底水平,并根据现有资料,估算了居民所受年有效剂量当量约为2.3mSv;其中原生γ辐射产生的约为0.54mSv,氡及其短寿命子体产生的约为0.8mSv。
This paper describes in general the natural radiation background level in China,andestimates,based on available data,the annual effective dose equivalent of the population to naturalradiation is some2.3 mSv,of which about 0.54 mSv is from original γ radiation and about 0.8 mSvfrom radon and its short-lived daughters.
