Advocates fight for cell phone radiation warning labels

Mindy Brown is on a crusade to warn people about radiation from cell phones. Brown has no doubt that cell-phone radiation triggers cancerous brain tumors. Brown's activism is raising awareness about a controversial issue that has been percolating for years but is now heating up as lawmakers debate whether it's time to act. The scientific community is divided over health effects of the low levels of electromagnetic radiation emitted by the phones. The cell-phone industry maintains the phones are safe. In the end, researchers say, the safety debate likely will go on for years, while more and more people use the phones.
