An anonymous reader quotes a report from TechCrunch: New Studies from the National Institutes of Health -- specifically the National Toxicology Program -- find that cell phone radiation is potentially linked with certain forms of cancer, but they're far from conclusive. The results are complex and the studies have yet to be peer-reviewed, but some of the findings are clearly important enough to warrant public discussion. An early, partial version of this study teasing these effects appeared in 2016, but these are the full (draft) reports complete with data. Both papers note that "studies published to date have not demonstrated consistently increased incidences of tumors at any site associate with exposure to cell phone RFR [radio frequency radiation] in rats or mice." But the researchers felt that "based on the designs of the existing studies, it is difficult to definitively conclude that these negative results clearly indicate that cell phone RFR is not carcinogenic." 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 rodents were examined for various health effects after various durations, from 28 days to 2 years. At 1900 MHz: Equivocal evidence of carcinogenicity in lung, liver and other organ tissues in both male and female mice.
