Yes, I do not trust cell phone manufactures who tell us that cellphones are perfectly safe, and that we should not worry about the radiation the phones give off. I waited for years before I got a cell phone. With the nearly disappearance of street phone booths and boxes, having a cellphone has become a necessity.

Of course when I use a cellphone, I use an earplug with a long cord,  and I hold the phone as far from my body as possible. I only take the phone with me when I have to be near a phone.

Yesterday, Tuesday, San Francisco adopted a city ordinance requiring retailers to post the radiation levels of mobile phones. This city with progressive leaders is the first U.S. jurisdiction to respond to increased consumers concerns over the link between cellphone use and cancer. Several European countries are already warning cellphones users of the risks those cellphones pose for long-term users and children.

Kudos for San Francisco.
