Description

High-dose radiation is used for sterilization of medical equipment and food irradiation. For these purposes, dose control is very important because quality of irradiated products depends on the absorbed dose. National Institute of Advanced Industrial Science and Technology is developing the high-dose standard using an alanine dosimeter. The alanine dosimeter can determine the dose by quantifying the amount of radiation induced radicals using an electron spin resonance (ESR) spectrometer. This article introduces the outline of ESR measurement required to establish the high-dose dosimetry. (author)

Abstract (Japanese)

日本でこれまで整備されてきた水吸収線量標準は,約200 Gyまでであり,それ以上の線量については海外の標準機関に依存している.大線量の放射線は,医療機器の滅菌や食品照射などに使用されており,これらの照射目的では,照射製品の品質が線量に依存するため,線量管理が非常に重要である.そのため,産業技術総合研究所ではアラニン線量計を用いた大線量標準の開発を進めている.アラニン線量計は,放射線照射によって生じたアラニンラジカルの量を,電子スピン共鳴(ESR)装置を用いて定量することで線量を求めることができる.本稿では,大線量標準を確立する上で必要なESR測定の概要について紹介する.(著者)
