No, it isn't. Researchers check for things like that. Solid state detectors and other devices are also not susceptible to such problems.
Jed, there are I'm sure devices not susceptible to hydrogen permeation. But many devices are susceptible for example like standard metal oxide thermocouples which unless properly encapsulated are highly sensitive to reducing atmospheres. Even proper encapsulation is relative. The whole point about H (and to a lesser extent D) is that it can get through pretty well all solids - you need something pretty good like a thick metal container to reduce contamination from exposure for long periods.
