Hi Ed:
Hardware that'd going into space and might be exposed to the Van Allen Belt
required special treatment of semiconductors.
https://en.wikipedia.org/wiki/Van_Allen_radiation_belt#Research
For example the Tunnel Diodes we used in microwave amplifiers where highly doped and the effect of a change of doping of
some particle was not a problem. But for semiconductors that were near intrinsic the effect was huge. For example a
diode that is Positive-Intrinsic-Negative (PIN) can be used as a radiation sensor. Also see:

axioms:
1. The extent to which you can fix or improve something will be limited by how
well you understand how it works.
2. Everybody, with no exceptions, holds false beliefs.

I have posted some stuff at the geigercounters group, related to the noise hits on the 417, so there is now some
parallel info there too, beginning here:

I'll have more experiment and design info to report in a couple days.
