Abstract

Overview

Nuclear medicine often isolates patients post-radiopharmaceutical injection, during which patients may use Wi-Fi-enabled devices. This study assesses the biological impacts of simultaneous gamma-ray and Wi-Fi exposure.

Findings

  • Fifty male Wistar rats were exposed to conditions involving only Wi-Fi, gamma radiation (99m Tc), or both for durations of 2, 24, and 72 hours.
  • Blood samples were analyzed for DNA double strand-breaks via gamma-H2Ax foci counting by flow cytometry.
  • Significant DNA damage was observed primarily after 72 hours of simultaneous exposure, highlighting an increase in health risks when subjected to both gamma rays and Wi-Fi.

Conclusion

The research conclusively shows that simultaneous exposure to Wi-Fi and gamma radiation significantly increases DNA breaks in peripheral blood lymphocytes—indicating potential health risks associated with combined radiations.
