Abstract

Electromagnetic radiation (EMR) emitted by mobile phones is known to cause neurological changes. This research was performed to examine CFRP shielding against 1800 MHz EMR mobile phone exposure on changes in spatial memory and oxidative stress in the cerebrum and hippocampus tissue. Male Wistar rats (n=27) were randomly categorized into 3 groups; control, EMR exposure, EMR exposure + CFRP shielding groups. Experimental groups were exposed to EMR (SAR=0.897 W/Kg) from an activated 1800 MHz mobile phone for 2 h/days for 30 days and using 4 layers of CFRP. Malondialdehyde (MDA) level and spatial memory were evaluated. Rats exposed to EMR without shielding showed reduced spatial memory and significantly higher MDA levels in both the cerebrum and hippocampus. In contrast, CFRP shielding improved outcomes, with increased spatial memory and lower MDA levels compared to unshielded EMR exposure. Statistical analysis confirmed significant differences in MDA levels in the cerebrum and hippocampus (p=0.00 for both), while spatial memory differences were not statistically significant (p=0.32). CFRP shielding is proven to reduce the negative impacts of 1800 MHz EMR emitted from mobile phone on spatial memory and MDA level of male Wistar rats brain tissue. © 2026 Farindra et al. cle distributed under th.
