re: #23 Teukka

That’s the thing, there isn’t that. Intense radiation like that affects electronics, and the more miniaturized it is, the greater the effect. Like you saw in the video clip, that’s gamma hitting the image sensor. BTW, I’ve seen some alt-reality afficianados claim that nukes have been used in Yemen, yet none of the videos display that effect, which they would if in the vicinity of a nuclear blast, if the camera wouldn’t crash from the EMP, that is.

Metals get neutron activated and their properties change, usually for the worse, metals such as cables the robots themselves.
Same with hydraulics, neutron activation and derating of the hydraulic oil.
Same with plastics, such as cable isolation and wheels.
Sure, you have more efficient shielding these days, such as Graded-Z shielding, but that only help so so much.
Also, to further complicate things, in that harsh a gamma environment, you also have Bremsstrahlung caused by gamma rays hitting stuff.

Exactly, generally the only way to shield sensors from “seeing” higher frequencies than they are optimally designed to detect is via the properties of the optics and filters placed in front, and gamma is an absolute motherfucker that pretty much just punches through everything. This is why almost all practical and semi-affordable thermal wavelength sensors are based on micro-bolometers positioned behind germanium metalloid lenses, which have a curious “window” in the thermal range but become conveniently opaque in what we call “optical” (ie detectable by the human eye), near IR (not detectable by humans but not quite “thermal”) and UV frequencies.
