The long-awaited results ofย a $25 million National Institutes of Healthย study on the effects of cellphone radio-frequency radiation exposureย on animals is out, and the results are mixed. They showed a higher risk of tumors, DNA or tissue damage, and lower body weight in some groups of rodents, butย no obviousย ill effect inย others and no clear implications for human health.

The new NIH study showed tumors in rats and mice inย other parts of the body โ the brain, prostate, liver and pancreas โ but the scientists said it was unclear whether those were related to the radiation.
Theย experiment involvedย placing rats and mice into special chambersย and exposing them to levels of radiation that mimic 2G and 3G phones, which were standard when the study was launched, for nine hours a day.

The Food and Drug Administration, which commissioned the study, released a statement describing โtheย mostly equivocal, or ambiguous, evidence that whole body radio-frequency energy exposures given to rats or mice in the study actually caused cancer in these animals.โ
