In the field of atomic energy and radiation utilization, radiation risk is considered as one of the social uneasy factors. About the perception of risks, there is a gap between experts and general public (non-experts). It is said that the general public tends to be going to judge risk from intuitive fear and a visible concrete instance whereas the experts judge it scientifically. A company, an administration or experts should disclose relating information about the risks and communicate interactively with the stakeholders to find the way to solve the problem with thinking together. This process is called “risk communication”. The role of the expert is important on enforcement of risk communication. They should be required to explain the information on the risks with plain words to help stakeholders understand the risks properly. The Japan Health Physics Society (JHPS) is the largest academic society for radiation protection professionals in Japan, and one of its missions is supposed to convey accurate and trustworthy information about the radiation risk to the general public. The expert group on risk communication of ionizing radiation of the JHPS has worked for the purpose of summarizing the fundamental matters on radiation risk communication. “Lecture on risk communication for the members of the JHPS.” which has been up on the JHPS web-site, and the symposium of “For better understanding of radiation risk.” are a part of the activities. The expert group proposes that the JHPS should enlighten the members continuously for being interested in and practicing risk communication of radiation.

比較的高い線量を照射したイメージングプレートでは、消去不全現象及び浮き出し現象が生じる。消去不全現象で観察される光は光輝尽発光であることを確認し、従来考えられてきた600nm近傍の光で励起される準位の電子の他に、より短波長側の光によって励起される深い準位(290nm付近)に電子が局在することを示した。この電子がこれら二つの現象の原因であると推論し、UV光と白色蛍光灯とを同時照射する新消去法を開発した。本法により、未照射レベルまで完全に消去することができた。
