Abstract

Overview

The study investigates the pre-exposure of rats to radiofrequency electromagnetic fields and its potential mitigation effects on subsequent high doses of X-rays.

Objective

Exploration of the effects of non-ionizing RF radiation pre-exposure on survival rates, weight changes, food, and water consumption in lethally irradiated rats.

Materials and Methods

Case-control study design.
Use of commercial mobile phone (GSM, 900/1800 MHz) and a 2.4 GHz Wi-Fi router for RF pre-exposure.
Six experimental groups including control and various RF and X-ray exposure combinations.

Results

Significant decline in survival rates in X-ray exposed groups compared to control.
No significant change among the groups exposed to "mobile+8 Gy", "Wi-Fi+8 Gy", and 8 Gy X-rays alone in survival rates.
Significant impacts on food and water intake by both RF and X-Ray exposures.

Conclusion

Identification of a specific dose window necessary for the induction of adaptive response (AR) was not observed, indicating a potential lack of AR in this setup. However, the patterns suggest that similar to ionizing radiation, RF exposure potentially requires a minimum damage level to induce adaptive responses.
