Abstract

Radiation exposure of the personnel in the neutron therapy facility of KCCH cyclotron neutron system is discussed. In neutron therapy room, medical personnel is exposed to photons of the remanent induced radioactivity from the isocentric gantry in which targets and collimators are mounted. The radiation level of the neutron therapy room of KCCH cyclotron was acceptable and it decreased immediately after beam off. Personal exposure measured by individual monitor was far less than permissible level.
