I suppose you could try lining a closet with crumpled foil and see how you
feel inside.

I'm not sure if it will help if it's RF coming from powerlines, but it
should
be possible to reduce microwave levels if there are no gaps in the foil
(not easy... maybe a layer of flat foil first so you can be sure there are
no gaps.
