Note)
・The ages above are those as of March 31, 2015
・The values of the exposure dose and the number of the workers in the table above are subject to change, because there are times when APD data are replaced with monthly dose data measured by integral dosimeters. Or dose data of workers who wore only an integral dosimeter (ex., workers who entered only the Main Anti-earthquake Building) need to be updated in the table after the publication of the data.
*The seven workers that were not able to be contacted are classified as "Age unknown" because we do not know which age range they belonge to.
