[en] The postradiative survival rate was studied in one-day Artemia nauplii γ-irradiation in doses equal to 2.5; 5; 7.5; 10 Gy at medium temperatures of 15, 22, 25, 27⁰C, respectively. A relationship is established between the irradiation effect (stimulation or inhibition) and temperature of the medium. The analysis of Artemia survival rate for stages of development shows that age contributes to the Artemia survival rate, relative to control, dependences on temperature (direct) and on the irradiation dose (inverse). 2 references, 1 figure, 2 tables
