The radiocaesium activity was measured by the dosimeters which were fixed on a tree trunk. Radiocaesium activity concentration of bark was estimated by the measurement values and the counts–radioactivity conversion coefficient obtained by the Monte Carlo simulation. The estimated radiocaesium activity concentration of the bark showed a good agreement with that of bark which were sampled from surrounding trees of the dosimeters setting tree. It was suggested that the simple and easy dosimeter–based method could be a useful tool for measuring the radiocaesium activity of bark.}, pages = {242--247}, publisher = {High Energy Accelerator Research Organization (KEK)}, title = {ポケット線量計を用いた森林の放射線モニタリングの試み -スギ外樹皮の放射性Cs濃度の簡易推定-}, year = {2019} }
