摘　　要：氡暴露的剂量转换系数是表征单位时间单位平衡氡浓度暴露所致人体有效剂量的量,受环境参数和人体相关参数的影响。采用剂量学方法和流行病学方法都能给出氡暴露的剂量转换系数,但是不同方法给出的值存在较大差别。随着近些年新一轮流行病学调查数据的公布和剂量学方法的发展,关于两种评价方法的认可和不同评价方法给出的氡暴露的剂量转换系数值都有了新的较大的发展。回顾了氡暴露的剂量转换系数的变化历史,介绍了氡暴露的剂量转换系数的研究动态,并结合近些年在该方面的研究,指出了以后的研究方向。Radon dose conversion factor relates the effective dose due to radon exposure and is affected by environmental parameters and human-related parameters. This value can get through dosimetric approach and epidemiological approach, but quite different through different approaches. As in recent years, a new round of epidemiological survey data published and dosimetric approach developed fast, the approving of two different methods and the radon dose conversion factor value have been largely developed. This article reviews the changes of radon dose conversion factor, introduces its recently development and points out the future research direction and focus combined with our studies.
