摘要
最近,居民氡流行病学调查取得了明显的进展,氡致肺癌超额相对危险为0.16%/100Bqm-3。在执行氡行动标准时,应注意对住宅和工作场所中,行动水平的含义是不同的。暴露量限值和导出空气浓度均是针对个人的,不能作为工作场所(源)控制的主要依据,工作场所中氡浓度控制主要应根据辐射防护最优化和约束值确定。
In the recent past, remarkable progresses has been made in radon epidemiological investigation for human populations, with the radon-induced excess relative risk being 0. 16%/100 Bq m^-3. It should be noted, for implementing radon action standards, that the action levels are differently implicated for population dwellings and workplaces. The dose limits and the derived air concentration are provided for the individuals, both of which can not be used as the main basis for controlling workplaces （sources）. The controlling of radon concentrations should be based primarily on radiation protection optimization and constraints.
