Evaluation of the Thyroids of Offsprings Exposed to 2450 MHz Radiofrequency Radiation During Pregnancy: A Sixth Month Data

Abstract

Overview

This study aimed to determine whether exposure to radiofrequency radiation (RFR) emitted by wireless internet providers (2450 MHz) throughout the day during rats' pregnancy causes alterations in the thyroid tissues of their offspring.

Methodology

• Pregnant rats in the experimental group were exposed to 2450 MHz RFR (24 hours/day, pulse wave mode, 1 W output strength, simulating Wi-Fi waves).
• Offspring (n = 8 per group) were randomly selected from both control and experimental groups.
• At the end of the sixth month, thyroid tissues were collected for histopathological and biochemical evaluations.
• Statistical analysis was performed using Mann-Whitney U-tests and T-tests. Statistical significance was set at p < 0.05.

Findings

• There was a significant difference in mononuclear cell infiltration (p=0.03) and vascular increase (congestion) (p<0.001) between groups.
• No significant differences were observed for TUNEL-positive cell percentage (p=0.62) and H2A.X antibody levels (p=0.68) between control and experimental groups.

Conclusion

Exposure to 2450 MHz radiofrequency radiation during the prenatal period caused some changes, specifically an increase in mononuclear cell infiltration and vascular congestion in the thyroid tissue of rat offspring, indicating possible tissue-level effects. However, there were no statistically significant differences in TUNEL-positive cell percentage and H2A.X levels. This research adds to the body of evidence linking electromagnetic field exposure to potential biological effects, even if not all markers reached statistical significance.
