The dose per exposure unit of the short-lived radon and thoron decay products was calculated using a dosimetric approach. The calculations are based on a lung dose model with the structure that is related to the ICRP 66 respiratory tract model. The dose relevant parameters, unattached fraction of the decay product clusters (fp) and size distribution of the unattached and aerosol-attached decay products for different living and working places are reported. Taking into account these characteristics the dose conversion factors (DCF) of the radon and thoron decay products were estimated. In addition, the living and working places were divided concerning their aerosol parameters like particle number concentration and activity size distribution.
采用剂量测定方法计算了短寿命氡和钍衰变产物的每暴露单位剂量。这些计算基于一个与ICRP 66呼吸道模型相关结构的肺部剂量模型。报告了不同生活和工作场所的剂量相关参数，即衰变产物簇的未附着分数（fp）以及未附着和气溶胶附着衰变产物的尺寸分布。考虑到这些特征，估算了氡和钍衰变产物的剂量转换因子（DCF）。此外，还根据其气溶胶参数（如粒子数浓度和活度尺寸分布）对生活和工作场所进行了划分。
