View Original AbstractOne year of high-level cell phone radiation exposure caused blood chemistry changes in rats, even at levels deemed 'safe' by researchers.
Plain English Summary
Researchers exposed rats to cell phone radiation from both CDMA and WCDMA technologies (the frequencies used by older 2G and 3G networks) for 45 minutes daily over one full year. The exposure levels were set at 4 W/kg total, which is four times higher than current safety limits. While most health measures remained normal, the study found some changes in blood chemistry and blood cell counts, though no increase in tumors or overall illness.
Study Details
We investigated whether one-year, long-term, simultaneous exposure to code division multiple access (CDMA; 849 MHz) and wideband code division multiple access (WCDMA; 1.95 GHz) radiofrequencies (RF) would induce chronic illness in Sprague-Dawley (SD) rats.
Two groups of 40 SD rats (50% males and females in sham and exposed groups) were exposed to CDMA and...
The mortality patterns in male and female rats exposed to RF were compared with those found in gende...
Our results suggest that one-year chronic exposure to CDMA (849 MHz) and WCDMA (1.95 GHz) RF simultaneously at 2.0 W/kg for 45-min RF exposure periods (total, 4 W/kg) did not increase chronic illness in rats, although there were some altered parameters in the complete blood count and serum chemistry.
