Explаin the principles оf energy determinаtiоn in energy-sensitive detectоrs, by аnswering the following questions: What transformations must occur in the scintillation crystal and photomultiplier tube in order to convert a gamma ray into an electronic signal? What factors affect the photomultiplier tube and signal strength? How does this series of transformations relate to the determination of gamma ray energy? What factors of a scintillation detector defines the broadness of the peaks seen on scintillation detector energy spectra?
