摘　　要：目的以间接法估算我国四膳食类型地区代表城市成年男子摄入原生放射性核素所致内照射剂量。方法通过双份饭法采集天津、成都、镇江、太原四城市成年男子膳食样品,同时采集该城市大气样品。应用电感耦合等离子体质谱(ICP-MS)测定并计算Rb、U、Th等元素摄入量。结果结合文献,估算了四地区成年男子摄入原生放射性核素所致内照射剂量。结论四地区成年男子摄入原生放射性核素所致内照射剂量与以前估算值相近。Objective To estimate internal dose from primordial radionuclides for Chinese adult men in four areas by using indirect appoach. Methods With duplicate portion study, mixed diet samples were collected from adult man in the city of Tianjin,Chengdu,Zhenjiang and Taiyuan,inhalabe particle samples in air were also collected at the same time. The concentrations of rubidium, uranium, thorium in these samples were determined by Inductively coupled plasma mass spectrometry （ ICP - MS） , and the intake of them were calculated. Results The internal dose from primordial radionuelides for Chinese adult men in four areas were obtained combined with the literature. Conclusions The estimation values are similar to previous estimations.
