Computers fail first because the memory content gets corrupted. I can imagine, that power electronics will continue functioning despite radiation.

- magicalhippo 6y agoApparently regular MOSFETs are affected[1] by the total dose of ionizing radition (TDI) causing important parameters to change, such as threshold voltage (Vgt) and internal resistance (Rds). So it seems even power electronics are not safe[2], nor microcontrollers/microprocessors and other types of ICs.
