Abstract :
Spectrometric characteristics of ionizing radiation detectors based on Bi4Ge3O12 and CdWO4 scintillators were calculated depending on sizes, shape (rectangular or cylindrical) and reflector type. Unlike other known publications, allowance was made for the dependence of the diffuse reflection indicatrix on the light incidence angle which is of importance for forming the light flows. The calculated method is verified by the experimental statistics. The regions of sizes and gamma-ray energies are indicated where the rough or polished version of the reflecting surface is preferable
