Abstract

Evaluation of the Thyroids of Offsprings Exposed to 2450 MHz Radiofrequency Radiation During Pregnancy: A Sixth Month Data Ozyilmaz C, Oktay MF, Dasdag S, Ulukaya E, Genel ME, Tansuker HD, Emre F, Yeğin K. Evaluation of the Thyroids of Offsprings Exposed to 2450 MHz Radiofrequency Radiation During Pregnancy: A Sixth Month Data. Journal of International Dental & Medical Research, 2024, 17(2): 925-930. Abstract This study aimed to determine whether the exposure to radiofrequency emitted by wireless internet providers (2450 MHz) throughout the day during rats’ pregnancy causes a problem in the thyroid tissues of their offspring. The pregnant rats in the experimental group were exposed to radiofrequency radiation (RFR) (24 hours/day) at a 2450 MHz frequency in pulse wave mode with 1 W output strength by a generator simulating Wi-Fi waves. The offspring in the control and experimental groups were randomized selected (n:8). At the end of the sixth month, the thyroid tissues were removed and evaluated histopathologically and biochemically. Mann‒Whitney U-tests and T-tests were used for statistical analysis. The threshold for statistical significance was p <0.05. There was a significant difference in mononuclear cell infiltration (p=0.03) and vascular increase in congestion (p<0.001). There was no difference in the TUNEL-positive cell percentage (p=0.62) and H2A.X antibody levels (p=0.68) between the rats in the control and experimental groups. In this study, 2450 MHz RFR exposure during the prenatal period did not cause a statistically significant difference in terms of H2A.X levels and TUNEL-positive cell percentages in the thyroid tissue of rats.
