Claim Text:
1. A radiation detector for detecting high-energy radiation, comprising: a scintillator group of a plurality of scintillator elements with at least two scintillator elements of the plurality of scintillator elements, including a first scintillator element configured to convert first energy primary photons of incident primary radiation into first secondary photons according to a first characteristic emission spectrum of the first scintillator element, which includes a first peak, and a second scintillator element configured to convert second different energy primary photons of incident primary radiation into second secondary photons according to a second different characteristic emission spectrum of the second scintillator element, which includes a second different peak; at least two photodetectors, including a first photodiode configured to convert said first secondary photons into first electrical signals and a second photodiode configured to convert said second secondary photons into second electrical signals, wherein each photodetector includes a first electrode disposed on one side and a second electrode disposed on an opposite side; wherein said photodetectors have different absorption spectra and read out emission with a voltage applied across the first electrode and the second electrode; and wherein the at least two photodetectors are transparent to the incident second different energy primary radiation.
