Effects of 171 MHz Low-Intensity Electromagnetic Field on Glucocorticoid and Mineral Corticoid Activity of the Adrenal Glands of Rats
Abstract
Overview
A study was conducted to analyze the biological effects of a low-intensity electromagnetic field (EMF) at 171 MHz on rats. This research utilized a Transverse ElectroMagnetic exposure chamber for controlled experiments.
Findings
- Various exposure levels (15, 25, and 35 V/m) over 15 days were tested against sham-exposed controls.
- Exposure conditions and electromagnetic energy distribution were simulated to evaluate specific absorption rates (SAR) in rat phantoms.
- A biphasic biological response was observed, indicating time and energy-dependent effects.
- At a low SAR (~0.006 W/kg), stimulation of adrenal gland activity was noted, marked by changes in corticosterone and Na+ levels.
Conclusion
The study suggests that low-intensity EMF exposure might trigger a stress response in rats, characterized by increased adrenal activity. These findings emphasize the significance of understanding EMF's biological impact on living organisms.
