Radiation measuring device, radiation measuring method, radiation measuring program, internal body tissue movement method, and non-transitory recording medium

A radiation measuring device which is of a forceps type and which measures radiation from a body tissue, comprising:

• a pair of radiation detecting sections each of which includes a plurality of radiation detecting elements;
• and
• a correcting section which estimates a position of a source of radiation or a distribution of the position or both of the position and the distribution of the position from detection data obtained by the pair of radiation detecting sections and which corrects detection sensitivity of the pair of radiation detecting sections with respect to the radiation from the source with use of, in addition to the position of the source of the radiation or the distribution of the position or both of the position and the distribution of the position each of which has been estimated, a sensitivity correction table that includes reciprocals of values normalized based on a detection sensitivity distribution so that intensity of the source of the radiation becomes uniform, the detection sensitivity distribution being a distribution that has been obtained in advance and that varies depending on the position of the source of the radiation.
