DEVICE FOR MEASURING RADIATION INTENSITY OF SMALL SEALED RADIOACTIVE SOURCE FOR CANCER THERAPY

摘要

Disclosed is a device for measuring radiation intensity of small sealed radioactive sources for cancer therapy, capable of easily and accurately measuring radiation intensity of radioactive sources while a cartridge is packed in a sterilized state. Specifically disclosed is a device for measuring radiation intensity of radioactive sources (S) filled in a cartridge (C), which comprises a radiation intensity measuring means that measures radioactive rays emitted from the radioactive sources (S); a holding means (30) that holds the cartridge (C); and a moving means that moves the holding means (30) to the radiation intensity measuring means. The moving means includes a guiding unit that guides the movement of the holding means (30) such that the holding means (30) moves along a direction orthogonal to the axial direction of a slit (15h) and a moving unit that moves the holding means (30) such that all the radioactive sources filled in the cartridge (C) passes through a position where the slit (15h) is formed inside an accommodation space of an accommodating unit.
