Abstract

Overview

With the rapid advancement of technology, particularly the widespread implementation of 5G, concerns about the biosafety of radiofrequency radiation (RF-EMR) from these technologies on health have emerged. This research employed Drosophila melanogaster to simulate an environment subjected to 3.5 GHz RF-EMR at varying intensities.

Findings

  • Experimental setups included short-term and long-term exposure to 3.5 GHz RF-EMR at 0.1 W/m2, 1 W/m2, and 10 W/m2.
  • The activity and sleep cycles of male flies, both parent and F1 generation, were monitored.
  • Short-term exposure: Increased activity and reduced sleep duration.
  • Long-term exposure: Decreased activity, increased sleep duration, upregulated stress response genes, and altered neurotransmitter gene expression.

Conclusion

Long-term RF-EMR exposure induces a significant stress response and alters core biological functions such as the circadian rhythm and neurotransmission in flies, leading to reduced activity levels and improved sleep quality. This study underscores potential health risks associated with long-term exposure to RF-EMR from emerging telecommunications technologies.
