Comment: Outer space is not the limit (Score 4, Interesting) 312
From a radiation engineering point of view, outer space is not the most stringent environment. It is actually significantly more forgiving than a lot of useful earth orbits or the radiation belts of the gas giants (but of course, you can hardly replace a failed transistor in space...).
These "vacum tube like" diamond field emission devices have shown radiation tolerance from 10 to 100 Mrad (1 MGy in SI units), so we are more talking about the levels required for operation in nuclear reactors or close to the beam of particle accelerators.
