Abstract :
Spectrometric characteristics of ionizing radiation detectors based on Bi4Ge3O12 and CdWO4 scintillators were calculated as a function of size, shape (rectangular or cylindrical) and reflector type. Unlike previous work, allowance was made for the dependence of the diffuse reflection indicatrix on the light incidence angle which is of importance for light transfer in a scintillator. The calculation method was verified by the experimental statistics. The regions of parameters are derived where the rough or polished version of the reflecting surface is preferable
