Document Type and Number:

WIPO Patent Application WO/2023/243364

Kind Code:

A1

Abstract:

A radiation measuring device (1) is a forceps-type radiation measuring device (1) for measuring radiation from internal body tissue, and comprises: a pair of radiation detecting units (10) each provided with a plurality of radiation detecting elements; and an adjusting unit (20) for estimating a position of a radiation source from detected data acquired by the pair of radiation detecting units, and adjusting a detection sensitivity of the pair of radiation detecting units with respect to radiation on the basis of the estimated position of the radiation source.
