Cell phone radiation at regulatory limits showed no measurable damage to rats' inner ear function in this 4-week study.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to cell phone radiation at 900 and 1800 MHz frequencies for 2 hours daily over 4 weeks to test if it damaged their inner ear function. Using sensitive hearing tests that measure the health of cochlear hair cells (the tiny structures that convert sound waves into nerve signals), they found no differences between exposed and unexposed animals. This suggests that typical cell phone radiation levels may not directly harm the delicate hearing mechanisms in the inner ear.

Study Details

The aim of this study was to evaluate the cochlear functionality of Sprague-Dawley rats exposed to electromagnetic fields at the typical frequencies of GSM mobile phones (900 and 1800 MHz) by distortion product otoacoustic emissions, which are a well-known indicator of the status of the cochlea's outer hair cells

A population of 48 rats was divided into exposed and sham-exposed groups. Three sets of four loop an...

The analysis of the data shows no statistically significant differences between the audiological sig...
