Abstract:
1. A radiation detector that detects spatial distribution of a first radiation and a second radiation, the radiation detector comprising: a plurality of optical transducers, each of which converts the first radiation to a first light having a first wavelength, and converts the second radiation to a second light having a second wavelength; a shielding unit that is arranged between adjacent ones of the optical transducers to shield the first radiation, the second radiation, the first light, and the second light; a plurality of first photoelectric converters, each of which corresponds to a respective one of the optical transducers, and outputs a first electrical signal based on intensity of the first light; and a plurality of second photoelectric converters, each of which corresponds to a respective one of the optical transducers, and outputs a second electrical signal based on intensity of the second light.
