This laboratory study found no DNA damage in blood cells after 24-hour exposure to cell phone radiation, but doesn't address long-term real-world exposure effects.

Plain English Summary

Summary written for general audiences

Researchers exposed human blood cells to 900 MHz radiofrequency radiation (the same frequency used by GSM cell phones) for 24 hours at various power levels to see if it caused DNA damage or affected cell growth. The study found no evidence of genetic damage or harmful effects on the cells, even at exposure levels up to 10 watts per kilogram. Two independent laboratories confirmed these results using cells from 10 different healthy volunteers.

Study Details

The objective of this study was to investigate whether 24 h exposure to radiofrequency electromagnetic fields similar to those emitted by mobile phones induces genotoxic effects and/or effects on cell cycle kinetics in cultured human peripheral blood lymphocytes.

The effect of 900 MHz exposure (GSM signal) was evaluated at four specific absorption rates (SARs, 0...

The results obtained provided no evidence for the existence of genotoxic or cytotoxic effects in the...

These findings were confirmed in the two groups of five donors examined in the two laboratories and when the same slides were scored by two operators.

Quick Questions About This Study

No, 900 MHz GSM radiation does not cause genetic damage in human blood cells. A 2006 study exposed blood lymphocytes from 10 healthy volunteers to GSM signals for 24 hours at various power levels up to 10 watts per kilogram and found no DNA damage or harmful cellular effects.
No, 24-hour exposure to 900 MHz cell phone frequencies is not harmful to human lymphocytes. Research examining blood cells from healthy volunteers found no evidence of genetic damage or reduced cell growth, even at high exposure levels of 10 watts per kilogram.
No, GSM phone signals do not affect cell division in human blood. A controlled laboratory study found that 900 MHz radiofrequency radiation had no impact on cell proliferation rates in human peripheral blood lymphocytes, even after 24 hours of continuous exposure.
Researchers tested 900 MHz radiation at specific absorption rates up to 10 watts per kilogram. This 2006 interlaboratory study found no genotoxic or cytotoxic effects across the entire SAR range investigated, with results confirmed by two independent laboratories using different operators.
Yes, interlaboratory studies confirm that GSM radiation appears safe for human cells. Two independent laboratories examining the same 900 MHz exposures on blood lymphocytes from 10 donors reached identical conclusions, finding no evidence of DNA damage or cellular harm.
