Brain cells showed no genetic changes when exposed to WiFi-frequency radiation at levels five times higher than current phone safety limits.

Plain English Summary

Summary written for general audiences

Researchers exposed human brain cells (glial cells) to 2.45 GHz radiofrequency radiation at power levels up to 10 times higher than current safety limits for up to 24 hours. They used advanced genetic analysis to look for changes in how genes were expressed, but found no significant alterations. This suggests that even at high exposure levels, this type of RF radiation may not directly damage the genetic machinery of brain cells.

Study Details

We investigated the effects of exposure to RF fields (2.45 GHz, continuous wave) at specific absorption rate (SAR) of 1, 5, and 10 W/kg for 1, 4, and 24 h on gene expression in a normal human glial cell line, SVGp12, using DNA microarray.

Microarray analysis revealed 23 assigned gene spots and 5 non-assigned gene spots as prospective alt...

Under the experimental conditions used in this study, we found no evidence that exposure to RF fields affected gene expression in SVGp12 cells.
