Patent ID: 11346962

Abstract:
A radiation detector for detecting radiation and identifying the type thereof includes: a scintillator module formed by stacking a first scintillator emitting light in a first wavelength range by reacting with first radiation and a second scintillator emitting light in a second wavelength range by reacting with second radiation; a first optical filter attached to a region of the scintillator module and transmitting the light in the first wavelength range; a second optical filter attached to another region of the scintillator module and transmitting the light in the second wavelength range; a first photodetector sensing the light in the first wavelength range that has passed through the first optical filter; a second photodetector sensing the light in the second wavelength range that has passed through the second optical filter; and a controller determining radiation on the basis of sensing results by the first photodetector and the second photodetector.
