Biometric System: Study of Radiation on the Human Arm

Key Points

Radiation absorption was highest for Wi-Fi at 0.168 mW, showing minimal risk to human health.
Absorption levels for LTE and AM modulation registered at 0.050 mW, well below safety thresholds.
The research employed Vivaldi antennas in an anechoic chamber using a phantom arm for accurate measurements.
Study findings support that current exposure levels remain safe according to ICNIRP guidelines.

Abstract

The study assessed radiation power absorption in the 1.5 to 5 GHz range for Wi-Fi, LTE, and AM modulation, using three Vivaldi antennas in an anechoic chamber with a phantom arm made of animal bone, ballistic gel, and pigskin. Wi-Fi showed the highest absorption levels, but these values (0.168 mW and 0.050 mW) were below ICNIRP safety limits, indicating no significant risk to human health.
