発明の名称 (英語) BETA RAY DETECTOR AND BETA RAY REBUILDING METHOD
発明の概要(英語) [PROBLEMS] To provide a beta ray detector and a beta ray rebuilding method in which high detection efficiency of beta ray is achieved uniformly in a wider energy region as compared with that of a conventional beta ray detector while enhancing energy resolution. [MEANS FOR SOLVING PROBLEMS] The beta ray detector comprises an absorption scintillator (12) located oppositely to a specimen emitting beta ray and composed of an absorption material exhibiting high permeability and absorption probability of beta ray, a backscattering scintillator (14) located on the back of the absorption scintillator and composed of a backscattering material exhibiting low permeability and high backscattering rate of beta ray, and an energy detector (16) for rebuilding the energy and the detection position of beta ray emitted from a specimen by summing up the quantity of energy absorption of beta ray measured simultaneously by two types of scintillator.
