Since you're a numbers man, what kind of transmitters? What frequency(s)?
What signal strengths? How can you guarantee that it was "never even a
possibility".

I guarantee you, regardless of whether you take the covers off your mobile
phone or not, if you stick it in the microwave [DO NOT TRY THIS AT HOME], RF
energy WILL DESTROY semiconductors! (And just about everything else in the
phone too!).

My point is that it's a levels/frequencies based discussion.  Sure, there is
a background RF "noise" radiation present all the time. Sure electronics
goods should be designed to survive (in fact operate properly) at those
levels of RF.  But at the other end of the scale, you can (in theory) keep
cranking up the output of the RF, and eventually you will destroy
semiconductors.  I'm not saying they'll be the first components to fail, but
they will eventually fail.

David.
