It's not just the lack of evidence, the air around your wife is saturated with electromagnetic radiation at different wavelengths and powers, so unless you live far away from civilization or in a sheltered room or bunker than it is probably not radiation sensitivity, otherwise she would have suffered all the time.
And indeed, that doesn't really mean anything to anyone and it's amusing that you assert an anecdote in response to requests for data but I guess I expect too much from people these days. Just whatever sounds good and plausible to them is enough.
