What range of radio frequencies are civilians allowed to listen to on radio scanners?

Posted in Radio on 19.04.10

I want to buy a quality radio scanner, and am looking for a scanner that can detect all legally allowable frequencies. Anyone know what all the legally allowable frequencies are and perhaps a radio scanner that can pick up all of them or close to all of them? An answer would be highly appreciated. Thanks!
