This study found no DNA damage from 24-hour cell phone radiation exposure at realistic use levels in human immune cells.

Plain English Summary

Summary written for general audiences

Italian and British researchers exposed human immune cells (lymphocytes) to 935 MHz cell phone radiation for 24 hours at levels similar to what tissues experience during phone use. Using multiple DNA damage tests, they found no genetic damage from the radiation alone, and the radiation didn't make X-ray damage worse. This suggests that 24-hour exposure to this type of cell phone radiation doesn't directly break DNA or interfere with DNA repair.

Study Details

The possibility of genotoxicity of radiofrequency radiation (RFR) applied alone or in combination with x-rays was investigated in vitro using several assays on human lymphocytes. The chosen specific absorption rate (SAR) values are near the upper limit of actual energy absorption in localized tissue when persons use some cellular telephones. The purpose of the combined exposures was to examine whether RFR might act epigenetically by reducing the fidelity of repair of DNA damage caused by a well-characterized and established mutagen.

By comparison with appropriate sham-exposed and control samples, no effect of RFR alone could be fo...

This study has used several standard in vitro tests for chromosomal and DNA damage in Go human lymphocytes exposed in vitro to a combination of x-rays and RFR. It has comprehensively examined whether a 24-h continuous exposure to a 935 MHz GSM basic signal delivering SAR of 1 or 2 W/Kg is genotoxic per se or whether, it can influence the genotoxicity of the well-established clastogenic agent; x-radiation. Within the experimental parameters of the study in all instances no effect from the RFR signal was observed.

Quick Questions About This Study

No, a 2006 study found that 935 MHz GSM radiation at 1-2 W/kg for 24 hours caused no genetic damage to human lymphocytes (immune cells). Multiple DNA damage tests showed no chromosome breaks or DNA repair interference from this specific cellular frequency.
Research on human lymphocytes exposed to 935 MHz radiation for 24 continuous hours found no DNA damage. The study used standard genetic damage tests and detected no chromosome breaks or genetic harm at radiation levels similar to phone use.
No, 935 MHz GSM radiation does not increase X-ray DNA damage in human immune cells. Italian and British researchers found that cell phone radiation at this frequency did not enhance or worsen the genetic damage caused by X-rays.
A comprehensive 2006 study found no genotoxic effects from 935 MHz GSM radiation at 1-2 W/kg SAR levels. Human lymphocytes showed no DNA damage or chromosome breaks after 24-hour continuous exposure to these specific absorption rates.
Researchers used multiple standard DNA damage tests including chromosome aberration assays and DNA repair measurements on human lymphocytes. All tests consistently showed no genetic damage from 935 MHz GSM radiation at phone-use levels over 24 hours.
