Experimental measurements in the 800 MHz to 6 GHz band found attenuation of selected human body parts ranging from 4 dB to 23 dB. Attenuation differed by body part: chest showed the highest attenuation/absorption, head the lowest, and belly was intermediate.

Abstract

Interaction of selected parts of the human body with radio frequency fields B. Dolnik, E. Dolníková, E. Lumnitzer, E. Jurgovská, P. Liptai and L. Šárpataky. Interaction of selected parts of the human body with radio frequency fields. 2023 33rd International Conference Radioelektronika (RADIOELEKTRONIKA), Pardubice, Czech Republic, 2023, pp. 1-5, doi: 10.1109/RADIOELEKTRONIKA57919.2023.10109067. Abstract The issue of how electromagnetic waves interact with living organisms becomes increasingly critical with communication tools expansion that operates in the microwave region. This article deals with the human attenuation of microwaves in the 800 MHz to 6 GHz band. Experimental attenuation measurements focus on specific parts of the males aged 26 to 28: head, chest, and belly. Through measurements, we have confirmed that the attenuation of selected human body parts is from 4 dB to 23 dB. We found that the head, chest, and belly absorb electromagnetic waves differently. The chest absorbs electromagnetic waves the most and the head the least. Belly attenuation is in between head and chest attenuation. The measured data can serve as a basis for investigating the impact of microwaves on living organisms and for investigating microwave attenuation by human subjects in specific spaces. ieeexplore.ieee.org

Main findings

Experimental measurements in the 800 MHz to 6 GHz band found attenuation of selected human body parts ranging from 4 dB to 23 dB. Attenuation differed by body part: chest showed the highest attenuation/absorption, head the lowest, and belly was intermediate.

Outcomes measured

  • Microwave attenuation (dB) of human body parts (head, chest, belly) in 800 MHz to 6 GHz band
  • Comparative absorption/attenuation differences between body parts

Limitations

  • Sample size not reported in abstract
  • Only males aged 26 to 28 were measured
  • Only selected body parts (head, chest, belly) were assessed
  • No health outcomes assessed; study focuses on attenuation measurements
