Abstract

Workers inside transmission pylons with FM antenna arrays are likely to be exposed to near-field radiation exceeding reference levels for occupational exposure. In this study, the near-field behavior of 64 FM pylons was studied using a new methodology. Near-field characterization was done using field metrics without taking into account field sources' size or distance from field source. The specific absorption rate (SAR) was assessed in five hundred different near-field cases using a human phantom. Estimation formulas for both local and whole-body SAR are provided and validated numerically. Local and whole-body SAR are linked to electric field strength. © 2022 Bioelectromagnetics Society.

期刊介绍： Bioelectromagnetics is published by Wiley-Liss, Inc., for the Bioelectromagnetics Society and is the official journal of the Bioelectromagnetics Society and the European Bioelectromagnetics Association. It is a peer-reviewed, internationally circulated scientific journal that specializes in reporting original data on biological effects and applications of electromagnetic fields that range in frequency from zero hertz (static fields) to the terahertz undulations and visible light. Both experimental and clinical data are of interest to the journal''s readers as are theoretical papers or reviews that offer novel insights into or criticism of contemporary concepts and theories of field-body interactions. The Bioelectromagnetics Society, which sponsors the journal, also welcomes experimental or clinical papers on the domains of sonic and ultrasonic radiation.
