A device-disabling threat that normal threat sensors can't detect, even when those sensors have been deployed because of the chance of unusually high levels of that threat?

Yes, I'm allowed to be disturbed by that; why wouldn't you be?

Not at all.

The devices are tested for usual STP. Nothing else, unless specified. They are done so not for human comfort, but for tested conditions. No more.

If you want extreme conditions, pay through the nose.
