Abstract

Overview

In considering the rising prevalence of communication technologies, there is notable public concern regarding the detrimental effects of consistent exposure to radiation, particularly during pregnancy and the developmental stages of newborns.

Findings

This investigation utilized Sprague-Dawley rats to study the impact of constant (24 hours/day) exposure to 900 MHz GSM-modulated radiofrequency electromagnetic radiation (RF-EMR) during both prenatal and postnatal periods. The study specifically looked at the effects on liver oxidative stress and other hepatic parameters on postnatal days 1, 9, and 21. Key results include:

• A significant increase in oxidative stress markers such as MDA.
• Decreases in catalase (CAT) activity and mRNA expression during early postnatal days.
• Variable responses in activities and expressions of cytoSOD and mitoSOD.
• Expressions of Akt1, Nrf-2, and ICAM-1 similarly affected in exposed rats.

Conclusion

The continuous exposure to 900 MHz RF-EMR during critical developmental periods leads to an elevated oxidative stress status, which may predispose individuals to adverse health effects later in life. These findings add to the growing body of evidence linking electromagnetic field exposure to potential health risks.
