After Fukushima we were asked to provide specifications for acceptable operating environment radiation levels, after some negotiation they relented and gave us a figure we could test at, so engineers drove hardware to a spot with high background radiation and ran it for a couple of days off a generator to test.
The Japanese customers also insisted that each display on the hardware be the same shade of white, so they would all look nice in a datacenter, so our LCD displays have specifically graded white LEDs.
