Popis:	Laboratory studies were carried out to identify the effect of gamma radiation on mortality of the terrestrial mollusk F. Fruticum in the range of doses from 10 Gy to 100 Gy. Two age groups of mollusks were studied: fingerlings (0-1 years) and mature individuals. It is found that the use of terrestrial mollusks of the first age group for laboratory experiments is impractical due to their high sensitivity to changes in environmental parameters. The LD50/60 value is determined for mollusks of second age group as 60.7-119.3 Gy. The time dependence of the change in the mortality of the mollusks was revealed. An increase in the dose of irradiation leads to an increase in the mortality of terrestrial mollusks irradiated at medium and high doses in eleven months after exposure. The effect of low doses on the mortality rate is observed in eight months after exposure.
