This study investigated the effect of 900 MHz Radio frequency radiation (RF) from digital mobile telephone on the brain of Albino wistar rats. Twelve (12) male rats were used for the study divided into 3 groups of 4 rats each. Group A and Group B were exposed to 8 hours/day and 4 hours/day mobile phone radiation for 2 months respectively while Group C served as control. Genomic DNA (Deoxyribonucleic acid) fragmentation was accessed by agarose elecetrophoresis and histological study was conducted to check the structural changes in the brain tissue after exposure to the radiation for the period. The result showed that there was no observable DNA damage in the brain of rats. Alterations such as congestion of the cerebral blood vessels and presence of numerous spongiform vacuoles in the neuropil of the brain tissues of the exposed rats were observed. We concluded that exposure to mobile phone radiation can modify brain structure at tissue level but not at DNA level.
