To identify activated areas in electrostatic accelerator facilities and to develop strategies for safety decommissioning them, four accelerator facilities were selected and the induced activity caused by charged particles and secondary neutrons on the accelerator and its surrounding areas before and after performing experiments was measured. We also measure neutron flux during experiments....

We are working on the research for establishment of more reasonable decommissioning process of accelerator facilities with the aid of Japan Nuclear Regulation Authority. In this research, there are three important issues: (1) clarification of the target facilities and accelerators for assessment of activation, (2) development of novel technique for assessment of activation, and (3) provide a...

54. Evaluation of Activated Areas in the Particle Radiotherapy Facilities

Recently, number of particle radiotherapy hospitals is increasing in Japan. Accelerators for several hundred MeV proton and/or carbon beam irradiation are used. In case of decommissioning these facilities, it is important to estimate the radioactivity induced in the accelerator room. Three types of accelerator facilities, such as proton acceleration by cyclotron, proton acceleration by...
