Summary

Peculiarities of registration effectiveness of scintillation detectors NaI(Tl), in construction of which there is a thick lead shield around a crystal, with Al diaphragm for gamma rays transmitting have been inves-tigated. It was discovered, that in contrast to usual decreasing of effectiveness with rising of energy, the ef-fectiveness of investigated detectors begin to rise, beginning from energies ~ 1200 keV.

Keywords: gamma rays, detector, effectiveness, lead shield.
