48. 尽管在根据矿工研究得出的氡照射风险进行推算以评估家庭中的氡照射风险方面存在着重大不确定性，但根据矿工研究所得出的风险度与根据住宅案例控制研究得出的风险度却非常吻合。近来对欧洲和北美住宅案例控制研究进行了汇总，从而为评估长期住宅氡辐射所造成的风险提供了一个直接方法。根据当前的资料，委员会考虑使用通过汇总研究得出的以测量调整的风险系数来作为一个适当的基础，据此估计人们在家中受到氡辐射后所面临的风险。
48. Although there are major uncertainties in extrapolating the risks of exposure to radon from the studies of miners to assessing risks in the home, there is remarkably good agreement between the risk factors derived from studies of miners and those derived from residential case control studies. The recent pooling of residential case control studies in Europe and North America now provides a direct method for estimating the risks from long-term residential exposure to radon. On the basis of current information, the Committee considers the use of measurement-adjusted risk coefficients from pooling studies to be an appropriate basis for estimating the risks to people at home due to exposure to radon.
