Animal Study Finds No Evidence of Harm From Cellular Phones
A study of rats exposed to intensive radiation designed to simulate heavy exposure to the electromagnetic fields of cellular phones found no evidence to support claims that such exposure could cause cancer or other ills.
The study exposed the rats to levels of electromagnetic fields that people would receive from a cellular phone. The rats were exposed to such radiation for four hours a day, five days a week, for two years to simulate the exposure that an extremely heavy cell phone user might receive. But at the conclusion of the study, researchers found no signs of increased risk of cancer in any of the 31 tissues they examined.
Researcher Joseph Roti Roti, a professor of radiation oncology at the Washington University School of Medicine told the BBC,
We tried to mimic a high level of exposure that humans might experience. We found no statistically significant increases in any tumor type, including brain, liver, lung or kidney, compared to the control group.
The BBC reported that such research is consistent with similar studies performed in the 1970s and 1980s that found no ill effects caused by exposure of cellular phone radiation in animals. The Washington University study was funded by the cellular phone industry.
