This document outlines a study that will investigate the effect of electromagnetic contamination on memory. Rats will be divided into two groups, with one group exposed to electromagnetic waves and the other group not exposed. Both groups will undergo memory tests using a Morris water maze. The time it takes each rat to find a hidden platform will be measured and compared between the groups. The goal is to determine if exposure to electromagnetic contamination affects memory by comparing the memory test results between the exposed and unexposed rat groups.
