I think they are also inherently are more background radiation tolerant. But why they have whatever tolerance they have is not really the question. The question is, just how hard are they?
If they have parts that are 100 krad tolerant, then there is a good chance all their parts are (probably come off the same wafer). They just have more paperwork with them, hence the extra cost. Assuming the cost delta is significant, I'd try the less expensive version and test it.

All of the Peregrine products are SoS but they have more expensive versions of some that are good for a 100 krad total dose.

SOS technology parts are inherently rad-hard.
In the sense that they are latchup-immune.
