RF radiation at cell phone levels caused chromosome damage in human cells without heating, challenging current safety standards.

Plain English Summary

Summary written for general audiences

Researchers exposed human blood cells to 800 MHz radiofrequency radiation (similar to cell phone frequencies) for 72 hours at levels close to current safety limits. They found significant increases in chromosome abnormalities called aneuploidy, where cells had the wrong number of chromosomes. This type of genetic damage can contribute to cancer development and other health problems.

Why This Matters

This study provides compelling evidence that RF radiation can cause genetic damage at exposure levels close to current safety guidelines. The SAR levels tested (2.9 and 4.1 W/kg) are within range of what your cell phone produces during calls, yet caused measurable chromosome damage in human cells. What makes this research particularly significant is that the effects occurred without heating the cells, challenging the industry's long-held position that only thermal effects matter. The researchers carefully controlled for temperature, demonstrating these were true biological effects of the radiation itself. This adds to a growing body of evidence suggesting our current safety standards may not adequately protect against genetic damage from chronic RF exposure.

These results contribute to the assessment of potential health risks after continuous chronic exposure to RF radiation at SARs close to the current levels set by ICNIRP guidelines.
