Cell Phones and Radiation Exposure
Friday, July 9th, 2010Researchers recently examined the amount of radiofrequency (RF) exposure cell phone users undergo in various scenarios. The findings, published in the Journal of Exposure Science and Environmental Epidemiology, show that older analog technology produced the highest RF levels. Of the various digital communications networks used by cell phones CDMA networks had the lowest RF (major carriers include Sprint PCS, Verizon and Virgin Mobile) while with GSM (AT&T and T-Mobile) and TDMA (major US carriers have left this system) showing similar intermediate levels. Generally users are exposed to higher RF power output in rural areas.

Radiofrequency is a form of electromagnetic radiation. The National Cancer Institute states that there is no known links between cancer risk and RF, but research is still ongoing. ( Source: http://www.cancer.gov/cancertopics/factsheet/Risk/cellphones)
The Environmental Working Group published a report on Cell Phones and Radiation Exposure and recommends specific makes and models.
A report published in the October 11, 2009 issue of the International Journal of Low Radiation added evidence to a protective effect for Ginkgo biloba against radiation damage. Ginkgo biloba is a tree species whose leaves have been used for centuries in Chinese medicine. Ginkgo leaf extract contains antioxidant compounds called ginkgolides and bilobalides which help scavenge free radicals that attack nearly all components of the cell, including DNA.
