There also are possible effects not mediated by temperature rise,
although the best documented effect, microwave hearing, isn't known
to occur under the conditions described.
As far as I have seen hearing of this a little more than casually,
Pulsed microwave radiation (as in what is usual for those exposed to
land and ship military/aviation radars) has thermal effects - as in
thermal expansion that is normally negligibale except it occurs at rates
to an extent that has acoustic effects that are detected by human hearing
mechanisms.

A little aluminum foil should fix it . . ..

And it is well enough known among many of those who have to work close
to radar transmitters that this is an actual effect, and it is a warning
sign - it may be not easy to judge whether an exposure resulting in this
effect can cause two worse effects:
1. The microwave radiation cooks the lenses of the eyes - which are
significantly human body organs not closely connected to the bloodstream!
(This damage mode requires a temperature rise to whatever temperature
causes this damage - a temperature rise of at least several degrees C).
2. If the human brain experiences even a small (just a degree or two,
maybe less) temperature rise that occurs within a few seconds, it can
malfunction.
In extreme cases, a radar troubleshooter can get knocked out and stop
breathing and die on the job from his brain (or parts of it) suddenly
warming up a degree or two.
Otherwise, nobody has shown largely-non-disprovable cause for concern
for low level microwave irradiation!
