摘要：
This paper describes the evolution of different commercial microprocessor supervisory circuits under neutron and gamma radiation. After the irradiation, the tested devices showed some interesting changes: an increase of supply current and the period of watchdog timer. It was also observed that threshold voltage hysteresis and the shift of TTL trigger level appeared in some devices.
