Re: Surely,...
Its been known for many years that tinfoil helmets don't block most R/F freuqencies and can actually enhance them in the 1-3GHz range. Aluminium foil isn't a very good shielding material anyway, you'd probably be better off with a mesh of some sort like metallic screen door material.
Personally I find foil most useful for reflecting surplus infra-red radiation and containng undesirable aqueous emissions while cooking.
