wireless, safe or not?

[comp builder]

I read in a paper (i think it was the sentinel, local papaer for staffordshire) that head teachers want wireless out of schools until they have checked wether it has any side effects.
As far as i am aware though, they run off a very high frequency radio wave (2.4GHZ i think). If this is the case then surely they're safe. The radio runs off this (although a much lower frequency i think) and remote control cars run off this (27mhz, 40mhz and 2.4ghz). Just seems a no brainer really.
Or is there something more to the wireless?

my router is in my bedroom and i mainly use my laptop in the living room (2 floors down from the router).
Is it dangerous having the router in my bedroom as i presme (while it is still on) it is still emitting the wireless signal. So wifi is safe?
someone says about using it once a week, but i use it everyday, is this a problem?
