Study Details

The effects of chronic and repeated radiofrequency electromagnetic radiation (RFEMR) exposure on spatial cognition and hippocampal architecture were investigated in prepubescent rats.

Four weeks old male Wistar rats were exposed to RF-EMR (900 MHz; SAR-1.15 W/kg with peak power densi...

Progressive learning abilities were found to be decreased in RF-EMR exposed rats. Memory retention t...
