Summary

This study validates 5G millimeter-wave (MMW) exposure guidelines. In rats, absorbed power density (APD) correlated with skin temperature rise, supporting the 200 W/m² threshold to prevent adverse health effects.

Area of Science:

  • Biophysics
  • Electromagnetic field exposure
  • Public health

Background:

  • Widespread 5G millimeter-wave (MMW) use raises health concerns.
  • International guidelines use 200 W/m² absorbed power density (APD) to limit tissue temperature rise to 5°C.
  • APD is simulation-based; in vivo validation is needed.

Purpose of the Study:

  • Investigate the in vivo relationship between APD and skin temperature rise.
  • Validate current MMW exposure guidelines.

Main Methods:

  • Rats' dorsal skin exposed to 26.5 GHz quasi-MMW (qMMW) for 18 min.
  • APD levels ranged from 0-500 W/m².
  • Simultaneous skin and rectal temperature measurements.

Main Results:

  • Local skin temperature increased up to 11.3°C at 500 W/m² APD.
  • Rectal temperature showed minimal increase (0.6°C), indicating localized effects.
  • Significant APD-skin temperature correlation found; <5°C rise estimated at 200 W/m² APD.

Conclusions:

  • The 200 W/m² operational threshold for MMW exposure guidelines is supported by these rat experiments.
  • Findings suggest current guidelines are valid under tested conditions.
