ABSTRACT:
A process for extending the operating period of a circuit having MOS components exposed to gamma radiation wherein identical systems (10a, 10b, 10c) forming the circuit are switched on in turn. Exposure to radiation causes the MOS components to deteriorate. However, when one of the systems are "on", the others are "off" and are able to partly or fully recover their original characteristics. The systems are operated for a period of time shorter than that required for deterioration. Specific application to intervention robotics on nuclear sites and space installations.
