計測・線量評価部

計測・線量評価部は、放射線に関連する様々な研究開発の基盤となる放射線計測及び線量評価に関する基礎・応用研究を包括的に行っています。
具体的な研究内容としては、最新技術を利用した放射線計測技術に関する研究開発、多様な放射線被ばく事故時において正確かつ迅速に患者の被ばく線量評価を行うための研究開発、すなわち、物理学的線量評価及び生物学的線量評価に関する研究開発など幅広い分野に渡ります。

＜組織構成＞
​・​​物理線量評価グループ
・生物線量評価グループ
・放射線計測グループ
​・生活圏環境移行研究グループ

ARADOS（Asian Radiation Dosimetry Group) は、各研究機関の協力の下、自発的に構築されたアジア各国間の線量評価に関するネットワークであり、2015年より活動しています。
線量評価分野における研究開発の推進と、アジア域内の協力体制発展のプラットフォームとなることをその活動目的としています。
