International exposure guidelines such as ICNIRP and IEEE C95.1 standard are published to protect human from potential adverse health effect. These standards establish the limit for induced electric field, also called basic restriction. The permissible external field strength— known reference level—is then conservatively derived Though level is calculated assuming that body exposed or magnetic ...

The International Commission on Non-Ionizing Radiation Protection issued guidelines in 1998 for limiting public and occupational exposure to radiofrequency electromagnetic fields (100 kHz to 300 GHz). As part of the process of updating this advice, a 2-d workshop titled "A closer look at the thresholds of thermal damage" was held from 26-28 May 2015 in Istanbul to re-examine the thermal basis o...

Abstract This study assessed the radiofrequency electromagnetic fields (RF-EMF) exposure levels proximal to primary school structures in Mpumalanga province of South Africa. A calibrated Acoustimeter was used measure RF EMF at defined distance points 50 and 100m away from three mobile base stations, that provide a 4G network coverage. All measurements were obtained each one district municipalit...

One major source of controversy related to possible health effects radiofrequency radiation (RFR) is the large number reported statistically significant exposure, over entire RF part spectrum and a wide range exposure levels, even as agencies do not find clear evidence for hazards at levels within current IEEE ICNIRP limits. This Perspective considers 31 studies genetic damage produced by RFR f...

In this study, the external magnetic field emitted by a wireless power transfer (WPT) system and internal electric induced in human body models during recharging operations of compact vehicle (EV) are evaluated. The magneticfield is calculated with hybrid scheme coupling boundary element method surface impedance conditions order to fit multiscale open-boundary characteristics problem. A commerc...

The present work was focused on assessing the spatial exposure variability for pedestrians road, in close proximity to a car equipped with 5G-V2X antenna, operating at working frequency of 3.5 GHz and 3D beamforming capability. Indeed, Cooperative Intelligent Transportation Systems (C-ITS) will soon utilize 5G New-Radio (NR) wireless communication overcome limitations current V2X (Vehicle-to-Ev...
