Abstract

Overview

This study investigates the distribution of the whole-body averaged specific absorption rate (WBSAR) for the Chinese adult population exposed to environmental electromagnetic fields (EMFs) at current wireless communication frequencies. It employs a combination of stochastic dosimetry and sophisticated parametric human modelling techniques.

Methodology

Data collected from the National Physical Fitness and Health Database comprising 81,490 adults.
Use of a stochastic method with 40 deterministic simulations for generating gender-specific models.
Anatomically correct human models developed via a deformable human modelling technique driven by deep learning.

Findings

The study highlights the potential health effects of EMFs by estimating individual exposure levels. Significant gender-dependent variability in response to different frequencies was noted, reflecting variations in physique parameters like height and head circumference (HC).

Conclusion

The findings underscore the rigorous method used to characterize the WBSAR distribution across different demographics within the Chinese population. The guidelines of the International Commission on Non-Ionizing Radiation and Protection appear conservative according to the observed population exposure levels. This research advances the understanding of populational exposure to radiofrequency EMFs at currently used wireless communication frequencies.
