New studies from the National Institutes of Health (NIH) links cell phone radiation to particularly aggressive forms of cancer.
Research conducted by the National Toxicology Program found that exposure to cell phone RFR [radio frequency radiation] is consistently linked to an increase in tumors.
Techcrunch.com reports: The studies exposed mice and rats to both 900 MHz and 1900 Mhz wavelength radio waves (each frequency being its own experiment) for about 9 hours per day, at various strengths ranging from 1 to 10 watts per kilogram. For comparison, the general limit the FCC imposes for exposure is 0.08 W/kg; the absolute maximum allowed, for the extremities of people with occupational exposures, is 20 W/kg for no longer than 6 minutes. So they were really blasting these mice.
“The levels and duration of exposure to RFR were much greater than what people experience with even the highest level of cell phone use, and exposed the rodents’ whole bodies. So, these findings should not be directly extrapolated to human cell phone usage,” explained NTP senior scientist John Bucher in a news release accompanying the papers. “We note, however, that the tumors we saw in these studies are similar to tumors previously reported in some studies of frequent cell phone users.”
The rodents were examined for various health effects after various durations, from 28 days to 2 years.
Before I state the conclusions, a note on terminology. “Equivocal evidence” is just above “no evidence” on the official scale, meaning “showing a marginal increase of neoplasms that may be test agent related.” In other words, something statistically significant but ultimately still somewhat mysterious. “Some evidence” is above that, meaning a more measurable response, followed by the also self-explanatory “clear evidence.”
At 900 MHz:
Some evidence linking RFR with malignant schwannoma in the hearts of male rats, no evidence for same in female rats. Equivocal evidence linking exposure to malignant brain glioma in females. Other tumors of various types in both sexes “may have been related to cell phone RFR exposure,” meaning the link is unclear or numbers aren’t conclusive. Less serious “nonneoplastic lesions” were more frequent in exposed males and females.
At 1900 MHz:
Equivocal evidence of carcinogenicity in lung, liver and other organ tissues in both male and female mice.
Although I would hesitate to draw any major conclusions from these studies, it seems demonstrated that there is some link here, though the level of radiation was orders of magnitude beyond what a person would ever experience in day to day life. As the researchers point out, however, relatively short-term studies like this one do little to illuminate the potential for harm in long-term exposure, such as babies who have never notbeen bathed in RF radiation.
An interesting side note is that the radiation-exposed rodents of both types lived significantly longer than their control peers: 28 percent of the original control group survived the full 2 years, while about twice that amount (48-68 percent) survived in the exposed group.
Two explanations are proffered for this strange result: either the radiation somehow suppressed the “chronic progressive nephropathy” that these mice tend to suffer from as they age, or possibly reduced feed intake related to the radiation might have done it. Either way, no one is suggesting that the radiation is somehow salutary to the rodents’ constitutions.
The reports and data run to hundreds of pages, so this is only a quick look by a non-expert. You can look over the full reports and supplemental materials here, but as this is a major study you can also expect replication, analysis and criticism from all quarters soon, including a scheduled external expert review organized by the NTP in March.
