Provided is a device for neutron capture therapy, capable of measuring a neutron dose in real time while suppressing reduction in measurement accuracy of a neutron beam. The device for the neutron capture therapy includes: a real-time dose output unit (40) including a scintillation detector (41) for detecting a neutron beam (N) and outputting a signal in real time, and a neutron dose output unit (44) for converting the signal, outputted from the scintillation detector (41), into a neutron dose using a correction coefficient (45) and outputting the neutron dose in real time; and a correction coefficient setting unit for setting the correction coefficient (45). The correction coefficient setting unit includes a gamma ray detection section for detecting a gamma ray generated from a gold wire activated by irradiation of the neutron beam, and modifies the correction coefficient (45) based on a signal outputted from the scintillation detector (41) by irradiation of the neutron beam, and a dose of the neutron beam obtained based on the gamma ray detected by the gamma ray detection section. |
