Cell phone radiation showed no DNA damage in mice at levels exceeding typical phone use by 15-30 times.

Plain English Summary

Summary written for general audiences

Researchers exposed mice to cell phone radiation (GSM and DCS frequencies) for 2 hours daily over 1 and 6 weeks to test whether it causes DNA damage in blood cells and other tissues. They found no increase in micronuclei (tiny fragments that indicate genetic damage) in any of the cell types examined, even at radiation levels up to 33.2 mW/g. This suggests that cell phone-type radiation at these exposure levels does not cause detectable genetic damage in mice.

Study Details

The aim of this study was to examine the possible induction of micronuclei in erythrocytes of the peripheral blood and bone marrow and in keratinocytes and spleen lymphocytes of mice exposed to radiofrequency (RF) radiation for 2 h per day over periods of 1 and 6 weeks, respectively

The applied signal simulated the exposure from GSM900 and DCS1800 handsets, including the low-freque...

Exposure levels for the 1- and 6-week studies were determined in a pretest to confirm that no therma...

Furthermore, the RF-field exposure of mice did not induce an increase in the number of micronuclei in erythrocytes of the bone marrow or peripheral blood, in keratinocytes, or in spleen lymphocytes compared to the sham-treated control.

Quick Questions About This Study

No, a 2005 study found that 902 MHz GSM radiation exposure for up to 6 weeks caused no increase in micronuclei formation in mouse blood cells, bone marrow, skin cells, or spleen lymphocytes, even at levels up to 33.2 mW/g.
Research shows 1747 MHz DCS radiation does not damage DNA in mice. After 6 weeks of 2-hour daily exposure, scientists found no genetic damage in any cell types examined, including blood cells and immune cells.
Studies testing both 1-week and 6-week exposure periods found that GSM and DCS cell phone radiation does not cause detectable genetic damage in mice at any timeframe, even with daily 2-hour exposures.
Researchers tested cell phone radiation up to 33.2 mW/g (milliwatts per gram) in mice and found no DNA damage. These levels were specifically chosen to avoid thermal heating effects that could influence genetic damage results.
No, keratinocytes (skin cells) from mouse tail roots showed no increase in micronuclei after exposure to both 902 MHz GSM and 1747 MHz DCS radiation for up to 6 weeks of daily 2-hour sessions.
