Abstract: Provided is a device for measuring the radiation intensity of small sealed radiation sources for cancer therapy the device being capable of efficiently and rapidly measuring multiple cartridges. A device for measuring the radiation intensity of multiple radiation sources (S) when the multiple radiation sources (S) are filled in a seed cartridge (SC) of a cartridge (C) the device being provided with: a holding means (10) capable of holding multiple cartridges (C); a radiation intensity measuring means (30) for measuring the radiation intensity released from the multiple radiation sources (S); and a movement means (20) for drawing the radiation intensity measuring means (30) closer to and away from the holding means (10). The radiation intensity measuring means (30) comprises a sensor (31) for measuring the radiation intensity and a screening member (35) with a slit (35h) provided so as to limit the radiation irradiated on the sensor (31). The movement means (20) is configured so as to be capable in the measuring state of relatively moving the radiation intensity measuring means (30) along the directions that the multiple radiation sources (S) are arranged.

Abstract: Provided is a device for measuring the radiation intensity of small sealed radiation sources for cancer therapy, the device being capable of efficiently and rapidly measuring multiple cartridges. A device for measuring the radiation intensity of multiple radiation sources (S) when the multiple radiation sources (S) are filled in a seed cartridge (SC) of a cartridge (C), the device being provided with: a holding means (10) capable of holding multiple cartridges (C); a radiation intensity-measuring means (30) for measuring the radiation intensity released from the multiple radiation sources (S); and a movement means (20) for drawing the radiation intensity-measuring means (30) closer to and away from the holding means (10). The radiation intensity-measuring means (30) comprises a sensor (31) for measuring the radiation intensity, and a screening member (35) with a slit (35h) provided so as to limit the radiation irradiated on the sensor (31). The movement means (20) is configured so as to be capable, in the measuring state, of relatively moving the radiation intensity-measuring means (30) along the directions that the multiple radiation sources (S) are arranged.
