What material can be used for shield against potentially dangerous

Follow-up Comment :
These are a beginning and most likely the lowest cost
first step. Plus they are the least intrusive and when
viewed from the exterior will not look like urban blight.

"This is the nickle spray I use for shielding:http://www.mgchemicals.com/products/841.html
There is a chart of non-ferous and ferous shielding, with the ferous
shield being 20db better at times."
CAUTION - Before using it on Interior Walls in Living Spaces
be sure to consult the MSDS Information for the Product and
the contact the Manufacture as to it's Safe Uses.

That paint is used for shield small plastic cases, not walls, though
it is available as a brus hon product. My comment is the ferrous
shielding is more effective. This again goes back to E&M,but my
recollection is a non-ferous shield only stops E, not H. A ferrous
shield, being electrically conductive as well, stops both fields.
Like I said, E&M is not my field of specialty, just my 2 cents.
