content: You can't blanket the country in 25-100 gigahertz because the atmosphere is opaque from ~10-~90 ghz with only small frequency holes. ~100 ghz is only useful for mmw laser and cannot be area broadcast in an efficient manner.  I'm not sure what you are talking about but you certainly have at least the details wrong. Also lets remember that radio wave radiation is electromechanical in nature, while particle radiation is chemical in nature and the two are unrelated.  One jiggles magnetically responsive molecules of just the right size and the other blows apart any molecules in it's path, sometimes destabilizing other atoms and causing more explosions as it goes.  Think of a gun vs a microwave oven, this isn't too far off.
