External dose evaluation based on detailed air dose rate measurements in living environments

Autor: Masaki Andoh, Masako Sato, Kimiaki Saito, Tetsuro Sato

Publikováno v: Journal of Environmental Radioactivity. 210:105973

A method was devised to estimate the realistic external doses of residents expected to return to their homes after evacuation orders are lifted. For 196 residents expected to return to six towns and villages, surveys were administered in FY 2014–20
