The total dose irradiation experiments were conducted on commercial triodes and MOS transistors. The impacts of different radiation temperature on the radiation effect were compared when the other conditions were identical. For the same total dose, the base current and current gain of the triode, and the threshold voltage of the MOS transistor exist a big discrepancy according to the different radiation temperature. When the total dose is 100 krad(Si) and the radiation temperature is 25, 70, 100°C, the current gain reduction of the NPN triode is 71, 89, 113, and the threshold voltage degradation of the NMOS transistor is 3.53, 2.8, 2.82 V, respectively.
