This replication study found no DNA damage from 2-hour microwave exposure at levels higher than typical cell phone use.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to 2450 MHz microwave radiation (the same frequency used in microwave ovens and some WiFi devices) for 2 hours to see if it would damage DNA in brain cells, as a previous study had suggested. They found no DNA damage in either the brain's cortex or hippocampus regions, contradicting the earlier research. This study suggests that short-term exposure to this type of radiation at moderate levels may not cause immediate genetic damage to brain cells.

Study Details

The present study was done to confirm the reported observation that low-intensity acute exposure to 2450 MHz radiation causes DNA single-strand breaks (Lai and Singh, Bioelectromagnetics 16, 207-210, 1995).

Male Sprague-Dawley rats weighing approximately 250 g were irradiated with 2450 MHz continuous-wave ...

Irrespective of whether the rats were euthanized by CO2 asphyxia or decapitated by guillotine, no si...

Furthermore, we did not confirm the observation that DNA damage is produced in cells of the rat cerebral cortex or the hippocampus after a 2-h exposure to 2450 MHz CW microwaves or at 4 h after the exposure.
