Re: handphone radiation effect
There have been many studies regarding cell phones and the radiation that they put off. I don't think you have to worry about it when it is just in your pocket, the radiation is apparent only when it is receiving a call.
At that time there is a signal emenating from the unit...and there is a tiny bit of radiation apparent.
I have one for emergency use...and have noticed that if I use it for more than 3 minutes, I get an ear ache. I have heard this is a common occurance with people like myself who have an inner ear imbalance. We are great receptacles for changes in the weather, atmospheric radiation and radio signals!
