Cellphone radiation and Cancer

There is an interesting graph in Scientific American (Via Bill Gross on Google+) showing the radiation spectrum of Cell phones and other devices. Click on the image to view full size.


Thing to note: As the graphic above shows, the radiation emitted in this region is nonionizing: it may heat molecules in the body but does not ionize them (that is, set electrons free). Ionizing radiation, which can tear molecules apart and therefore potentially damage DNA—is the greater worry.

In the comments of the discussion, someone pointed out this hand drawn Electromagnetic Spectrum which is very handy.

Finally, it is worthwhile checking out the total radiation that we can encounter in different events and their relative values.

Thanks for sharing this article.Cell phone are used for emergencies, but it's good to know the tips anyway. I'm sure my oldest will be begging for one soon!
