I recently got a laptop and it has a wireless internet connection on it. I also have a cellphone but I try to avoid using it for anything other than short calls (no conversations) because of the whole possibility of radiation or whatever causing brain cancer.
But then, no studies have yet linked cell phone radiation to brain cancer. 2.4 and 5.8 GHz cordless phones use even higher frequencies (in fact the 2.4 GHz phones are almost exactly the same frequency used in microwave ovens). If anything those should be more dangerous, but oddly no one is worried about them.
Well, there’s no proof that you’ll get cancer from cell phones but I’ll skip that.
While most wireless cards are rather high freq (2.4ghz, iirc) they don’t put out that much power and even if there was a real cancer risk from them having them up to your head a laptop is usually not that close to you.
That’s for sure. The lower-left portion of my laptop’s underside gets so toasty. Even worse is my adapter. I have the same computer as my friend (the laptop was included in our uni program) and my adapter gets about twice as hot as hers while in use. It’s so hot that I can’t firmly hold it for more than 5 seconds sometimes.
As for cellphones possibly being safe, I read that people just don’t know yet whether or not it is because cellphones haven’t been long enough for there to be enough people to conduct studies on.
