Cell phone radiation disrupts brain neurotransmitter balance at typical usage levels, with young brains showing effects faster than adult brains.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to 900 MHz cell phone radiation daily and found significant disruptions in brain neurotransmitters (chemical messengers between brain cells). Both adult and young animals showed altered brain chemistry patterns across multiple brain regions, potentially explaining neurological symptoms some people experience from mobile phone use.

Why This Matters

This study demonstrates that cell phone radiation at levels comparable to everyday use can disrupt the delicate chemical balance in the brain. The SAR level of 1.165 W/kg falls within the range of typical mobile phone emissions, making these findings directly relevant to human exposure. What's particularly concerning is that the researchers found different vulnerability patterns between adult and young animals, with young brains showing disruption after just one month compared to four months in adults. The disruption of neurotransmitter balance affects everything from mood and cognition to motor control and sleep patterns. This research adds to the growing body of evidence showing that our brains respond to radiofrequency radiation in measurable ways, even at exposure levels regulators currently consider safe.

Study Details

The present study aims to investigate the effect of one hour daily exposure to electromagnetic radiation (EMR) with frequency of 900 Mz (SAR 1.165 w/kg, power density 0.02 mW/cm2) on the levels of amino acid neurotransmitters in the midbrain, cerebellum and medulla of adult and young male albino rats.

Adult and young rats were divided into two main groups (treated and control). The treated group of b...

The present changes in amino acid concentrations may underlie the reported adverse effects of using mobile phones.
