1. A radiation diagnostic device comprising:
a first detector configured to detect Cherenkov light that is generated when radiation passes;
a second detector disposed to be opposed to the first detector on a side distant from a generation source of the radiation and configured to detect energy information of the radiation; and
processing circuitry configured to specify Compton scattering events detected by the second detector, and determine an event corresponding to an incident channel among the specified Compton scattering events based on a detection result obtained by the first detector.
