Pardon my ignorance, but how do you have "sensitivity" to microwaves and not just have these "serious consequences" from light which on the EM spectrum are "more radioactive" than microwaves?
You've never heard of a pacemaker?
This was only true for old pacemakers and even then improperly shieled microwave ovens. This problem isn't a big one today, short of the person climbing into the microwave and turning it on.
However, if the poster is wearing an older-model pacemaker it
might present a problem. But I would see that as a pretty big "might" as there's microwaves all around us in the air right now being emitted by things like RADARs and cell phones.
