An attempt was made to answer the question of the applicability of the Fermi-age approximation for homogeneous and heterogeneous media by making Monte Carlo compuiations and evaluating the results obtained. The distribution of absorbed energy of gamma radiation between the sources forming an infinlte lattice was compared with the energy absorbed in the surrounding medium, using the Strela'' computer for the calculations. Experimental data obtained with In- Ga irradiators and the telescoping fuel elements of the IRT reactor were used for calculating the distribution of the absorbed energy of the radiation. The irradiated surrounding medium consisted of water in both cases. It was concluded that the age approximation method may be used for infinite quasi-homogeneous systems. Good results were obtained also when the requirement of quasi- homogeneity was not clearly fulfilled, making it thus possible to avoid the Monte Carlo calculations. (TTT)
