Examination of the hardness course in luminescent crystals of NaI(Tl) naphthalene (activated by anthracene) and stilbene with respect to gamma- radiation dose rate is described. The photomultipler current was compared wfth the saturation current of a thimble ionization chamber that had no hardness course within the energy range in question. Gamma-radiation sources such as Sn/ sup 113(350 kev), Cs/sup 137/ (661 kev), and Co/sup 60/ (1.25 Mev) were used. All investigated crystals had the hardness course. The ratio of the photomultipler current to the chamber currert grows wfth higher gamma-radiatfon - energy for stilbene and naphthalene and drops for NaI(Tl). The minimum gamma- radiation dose rate that can be measured by the luminescent method was determined for a NaI(Tl) crystal. Feasibility of constructing a luminescent gamma-radiation dosimeter for measurfng a dose rate of 10/sup -9/ roentgen/sec is noted. (TCO)
