Most phones emit microwave radiation. Talk too long with your girl friend/boy friend and you will fry your brains out. Easy test: if the phone feels hot after a few minutes of yakking then the radiation is high. There were some research on radiation from hp and its effect on health .. but I think the hp companies hijacked the results and nothing much was done after that. Also, some hps have another hazard - they may explode while being charged.
