 note = {210Po and 210Pb contained in cigarettes might contribute to an increase in an effective dose. This article reports the effective dose of radionuclides to smokers based on results of a review of various parameters related to dose estimation for smokers. The annual effective dose to smokers was found to be 0.27 mSv year-1, which was lower than an intervention exemption level(1 mSv year-1)given in International Commission on Radiological Protection (ICRP Publ.82).},
