چکیده    Enormous quantities of radionuclides were released into the environment following the disastrous accident at the fukushima daiichi nuclear power plant (fdnpp) in march 2011. it is of great importance to determine the exposure doses received by the populations living in the radiologically affected areas; however,there has been significant difficulty in estimating the internal thyroid dose received through the intake of short-lived radionuclides (mainly,131i),because of the lack of early measurements on people. an estimation by the national institute of radiological sciences for 1 april 2012 to 31 march 2013 was thus performed using a combination of the following three sources: thyroid measurement data (131i) for 1080 children examined in the screening campaign,whole-body counter measurement data (134cs,137cs) for 3000 adults,and atmospheric transport dispersion model simulations. in this study,the residents of futaba town,iitate village and iwaki city were shown to have the highest thyroid equivalent dose,and their doses were estimated to be mostly below 30 msv. however,this result involved a lot of uncertainties and provided only representative values for the residents. the present paper outlines a more recent dose estimation and preliminary analyses of personal behavior data used in the new method. © 2016 the author 2016. published by oxford university press on behalf of the japan radiation research society and japanese society for radiation oncology.
