Statistical analysis of RF exposures depending on body surface area

With the wide application of 5G networks, the population’s exposure levels to RF-EMFs has also changed. The present work aimed to study the evaluation model of Chinese human body surface area (BSA) and electromagnetic dosimetry in the second generation to the fifth-generation wireless communication frequency band. Whole-body- averaged specific absorption rate (WBSAR) from 900 MHz to 3.5 GHz was calculated with the finite-difference time-domain method for front RF exposure configurations. This study highlights the importance of body surface area (BSA) in WBSAR characterization. The regression model was improved with human body models of different sizes, and the estimation error of WBSAR was about 5%. This study is suitable for establishing the statistical distribution of the WBSAR for Chinese population characterized by its morphology.
