The aim of the screening survey was to implement measurements for a large number of subjects with conventional NaI(Tl) scintillation survey meters. This protocol was applied to the screening survey for 1,149 children at five places in three municipalities (Kawamata Town, Iitate Village and Iwaki City). Among 1,080 children (excluding 69 subjects from evaluation), there were no subjects who exceeded a screening level (0.0002 mSv/h) corresponding to a thyroid equivalent dose of 100 mSv. No significant signals were detected for 55.4% of these subjects and the maximum dose was found to be 43 mSv. This paper presents details on the protocol as well as results of the screening survey.}, pages = {59--66}, publisher = {National Institute of Radiological Sciences}, title = {Screening survey on thyroid exposure for children after the fukushima daiichi nuclear power station accident}, volume = {1}, year = {2012} }
