Abstract: A radiation detection device according to an embodiment includes a scintillator and a processing circuit. The processing circuit measures transferred energy when scintillation is caused after a gamma ray incident on a scintillator generates Cherenkov light and estimates a Cherenkov angle based on the transferred energy.

Abstract: A radiation diagnosis device according to an embodiment includes a first detector and a second detector. The first detector detects Cherenkov light generated when a radiation passes. The second detector is provided to face the first detector on a side farther from a source of generating the radiation and detects the energy information of the radiation.
