Interaction of selected parts of the human body with radio frequency fields

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.
