NTP finds high exposure to RFR linked to cancer in male rats
The National Toxicology Program (NTP) has released its final reports from studies of rats and mice exposed to high levels of radio frequency radiation (RFR) like that used in 2G and 3G cell phones. NTP found clear evidence that exposed male rats developed cancerous heart tumors and some evidence that exposed male rats developed tumors in the brain and adrenal glands.
For female rats, and male and female mice, the researchers saw equivocal, or uncertain, evidence of associations between exposure to RFR and cancer. The final reports represent the consensus of NTP and an external expert panel who reviewed the studies in March.
The researchers said the results cannot be directly extrapolated to humans, but still provide important information about RFR, previously assumed by many to be safe. The animals received RFR across their whole bodies at levels and durations greater than what people typically experience. They were housed in chambers specifically built for these studies and were exposed intermittently, 10 minutes on and 10 minutes off, for a total of about nine hours a day for most of their natural lifetime. Additional studies are being planned. (VG)
