It's not definitively known whether cell phone radiation has a detrimental effect on health. While scientists try and figure it out, non-profit watchdog Environmental Working Group just released an analysis of 1,000 different cell phone models and their radiation levels. We talk with Richard Wiles, the group's spokesperson; and Louis Slesin, editor of Microwave News, an online publication that covers radiation issues.
If you're in the market for a new phone and concerned about radiation – though we should point out there's no firm evidence yet saying whether you should or should not be – you may want to consider Samsung, which has the phones that head the Top 10 list for lowest radiation.
