Plain English Summary
Italian researchers exposed human blood cells to cell phone radiation (1.95 GHz UMTS signal) for 24 hours, then hit them with X-rays to see if the RF exposure made the radiation damage worse. While the cell phone signals didn't increase the number of damaged cells, they did cause a small but measurable increase in the severity of chromosome damage within each affected cell at the higher exposure level (2.0 W/kg SAR). This suggests RF radiation might interfere with the cell's ability to repair DNA damage from other sources.
Study Details
This in vitro study was conducted to study the influence of 1.95 GHz UMTS modulated radio frequency exposure on X ray induced chromosome aberrations in human lymphocytes
Human peripheral blood lymphocytes were exposed in vitro to a UMTS signal (frequency carrier of 1.95...
No significant variations due to the UMTS exposure were found in the fraction of aberrant cells. How...
We conclude that, although the 1.95 GHz signal (UMTS modulated) does not exacerbate the yield of aberrant cells caused by ionizing radiation, the overall burden of X-ray-induced chromosomal damage per cell in first-mitosis lymphocytes may be enhanced at 2.0 W/kg SAR. Hence the SAR may either influence the repair of X-ray-induced DNA breaks or alter the cell death pathways of the damage response.
