Abstract 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 radionuclides for Chinese adult men in four areas were obtained combined with the literature. Conclusions The estimation values are similar to previous estimations.
