[en] The strength limits of the samples of epoxy containing the fillers and antioxidants have been measured after γ-irradiation at dose rate of 10^-1 / 10² Gy x s^-1. It is shown that different fillers, especially special cement, essentially increase radiation stability of the compound. Using 'Time-dose-temperature superposition' method and on the base of 'Recognition Theory' the limiting doses, corresponding to 25% losses of the yield strength (at electrical parameters conservation) were first determined by means of extrapolation to the dose rate of 10^-3 Gy x s^-1. It is ractically impossible to receive the value of the limiting dose in experiment for these conditions because it requires a very long time of irradiation of the samples to achieve necessary effect
