Your cellphone is killing you

The typical power output of a mobile phone is around 100 milliwatts, with the transmitting power varying depending on how far you are from the cell tower and other parameters. That doesn't really qualify as a "high-powered" transmitter. (What's your microwave oven then? A weapon of mass destruction?)
Now, it's possible that low-level microwave radiation can have adverse effects on health, but starting an article with this kind of overblown sensationalism doesn't bode well for its overall credibility.
Judging by most articles I've seen, the studies appear to be very typically limited to voice calls using the phone directly to ear, which isn't a common use case in for me.
