An apparatus includes a first radiation detector to generate a first signal when a first radiation level is exceeded and a second radiation detector to generate a second signal when a second radiation level is exceeded. The second radiation level is greater than the first radiation level. A first circuit is susceptible to soft errors at the first radiation level and a second circuit is susceptible to soft errors at the second radiation level. A control unit may suspend use of the first circuit and activate use of the second circuit if the first signal is received and the second signal is not received. The first and second circuits may be memory cells or logic circuits.
