Daily cell phone radiation exposure impaired mouse memory at levels below safety limits, with effects lasting weeks after exposure ended.

Plain English Summary

Summary written for general audiences

Researchers exposed mice to cell phone radiation (GSM 1.8 GHz) for 90 minutes daily to test effects on memory. After weeks of exposure, the mice showed significant problems with both spatial memory (remembering locations) and non-spatial memory (recognizing objects). These memory problems persisted for two weeks after radiation stopped but fully recovered after a month, suggesting the brain can repair this type of damage over time.

Why This Matters

This research provides compelling evidence that the type of radiation emitted by cell phones can impair memory formation and recall. The SAR level used (0.11 W/kg) is well below the FCC limit of 1.6 W/kg, yet still produced measurable cognitive effects after sustained daily exposure. What makes this study particularly significant is that it demonstrates both the cumulative nature of EMF effects and the brain's capacity for recovery when exposure is reduced. The fact that memory problems persisted for two weeks after exposure ended suggests these aren't just temporary disruptions but involve actual changes to brain function. The good news is the complete recovery observed after a month, indicating our brains have repair mechanisms that can address EMF-induced damage when given the opportunity.

Study Details

This study was designed to investigate the transient and cumulative impairments in spatial and non-spatial memory of C57Bl/6J mice exposed to GSM 1.8 GHz signal for 90 min daily by a typical cellular (mobile) phone at a specific absorption rate value of 0.11 W/kg.
