You're correct, I was imprecise -- I used "rad-hard" as a generic term for hardening/shielding against both ionizing radiation and electromagnetic/electrostatic fields/discharges. Strictly speaking, "rad-hard" is only about ionizing radiation (bit-flips, SEUs, totem-pole shoot-throughs, etc.).

In the 1980's I had the opportunity to design spacecraft gear which had to be rad-hard (in the proper sense), and some years later I was designing industrial/consumer gear which had to meet FCC high-voltage discharge (ESD) susceptibility requirements. In my earlier comment I conflated the two categories, which was incorrect, and I thank you for calling me on it.

I am impressed by your character and passion for truth. You've made my day. What a rare privilege it is to shared bandwidth. :)
