Foil is considered to be a good insulator since it has the ability to reflect radiation. However, aluminium foil is commonly used as a conductor and not an insulator.
Background radiation come from black body radiation which is mostly infrared and microwave. Background radiation is not harmful at all. Fear from background radiation come from confusion of the word radiation where we mostly concern nuclear radiation, but light is also a form of radiation and we live within the bright day light on a normal basis.
The most dangerous type of radiation is Nuclear radiation which is the one that should be most worried about.
Chemo radiation kill cancer cells.
The packet of electromagnetic radiation is the photon.
what is the essential concept of underlying radiation protection
Only the frequency of the communications carrier. Microwaves are electromagnetic radiation in the frequency range of 3 gigahertz to 300 gigahertz. Electromagnetic radiation above those frequencies are considered "optical" even though you can see only a small percentage of them with your eyes.

NO!

The ozone layer gives us the protection from radiation
The Freyssinet system provides leakage protection and radiation protection systems.
Lead, Water, Aluminum... something!
1. on earth light and radiation from space is filtered in the atmosphere, however when going out of the atmosphere radiation can become unpleasant.
