The Usage of the KUR Advanced Clinical Irradiation System for NCT under the KUR Continous Operation

Abstract

The remodeling construction of the KUR Heavy Water Neutron Irradiation Facility was completed at the end of March 1996, mainly for neutron capture therapy (NCT).1 The remodeled facility is available for the several “irradiation modes” whose neutron energy spectra are from almost pure thermal neutrons to epi-thermal neutrons, using the heavy water spectrum shifter and the thermal neutron filters of cadmium and boral. Clinical and experimental irradiations under the KUR continuous operation are possible using the radiation shield system and the equipment for the support of NCT clinical irradiations, such as a Remote Patient Carrier System with clinical collimators. We call the remodeled Heavy Water Facility and its accessory equipment, generally, “the KUR Advanced Clinical Irradiation System”.
