Cell phones use radiation in the microwave portion of the EM spectrum. Microwave radiation is non-ionizing. The only thing microwave radiation does is heat things, which is what these regulations are meant to protect consumers from in the first place.
I hate headlines like this because they fuel harmful misinformation. How many people are gonna come away from this headline thinking their phone might give them cancer? How many of those people are going to protest against further development of wireless technology from the misinformed position that non-ionizing EM radiation (such as visible light) can somehow cause cancer?
