This 90-day study found no memory impairment in rats exposed to 100 microT magnetic fields, levels similar to close appliance exposure.

Plain English Summary

Summary written for general audiences

Researchers exposed rats to 50 Hz magnetic fields at 100 microT (similar to levels near some electrical appliances) for 90 days while testing their spatial memory and learning abilities using a water maze. The magnetic field exposure did not impair the rats' ability to learn or remember spatial tasks, nor did it interfere with improvements from previous training. This suggests that this level of extremely low frequency magnetic field exposure does not harm basic learning and memory functions.

Study Details

This study aims to evaluate the effects of previous training and ELF-MF exposure on learning and memory using the Morris water maze (MWM).

Sprague-Dawley rats were subjected to MWM training, ELF-MF exposure (50 Hz, 100 microT), or ELF-MF e...

The data show that the rats exposed to training and ELF-MF with training performed better on spatial...
