Exposure Accelerator System for Biological Effect Experiment（NASBEE）を導入した。このシステムの特徴は、加速された水素及び重水素イオンをBe，Liターゲットに照射し、発生する高フルエンスの速中性子を生物・物理照射室だけでなくSpecific Pathogen free（特定病原菌未感染：SPF）環境下でマウス、ラット等に照射することができることである。この度生物照射実験に伴い、予備実験として最大強度を用いて生物照射室でマウス照射を行いマウスとマウスケージの放射化量を測定し、管理区域持ち出し限界である 130 count/minになるまでの時間を測定した。マウスへのトータル線量は1、3、7  Gyの3種類で、管理区域からの持ち出し可能時間は1 Gy 時で50分、3 Gyで8時間以上、7 Gy 時の場合は放射化が収まるまでに24時間以上必要となることが分かった。以上のことから、今後の使用運用上でマウスを持ち出す時には、鉛などの容器に入れ表面線量を下げなければいけない事が分かった。また照射サンプルの解剖等の作業は非密封RI施設であるRI棟で行っていただくように運用を変更した。","subitem_description_type":"Abstract"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata
