Abstract

Overview

The recent study highlights the concern of microwave (MW) radiation and its health implications. The research focuses on the effects of 10 GHz MW radiation on rat skin exposed to specific power densities over a period.

Methodology

Exposure settings included 3 hours daily for 30 days at power densities of 5.23 ± 0.25 and 10.01 ± 0.15 mW/cm2. The comparison was made against sham-irradiated controls, particularly noting the level doubled from ICNIRP-2020 occupational reference for humans.

Findings

  • Infrared thermography indicated increase in skin temperature.
  • Significant oxidative stress markers and inflammatory responses were observed.
  • Metabolic changes, including alterations in hexokinase and lactate dehydrogenase activities.
  • Cell survival and stress-response signaling also showed significant variations.

Conclusion

Significant molecular changes in rat skin suggest potential health risks from continuous-wave mode MW exposure at 10 GHz. Study emphasizes the need for further scientific investigation on prolonged exposures, especially in pulsed-mode.
