Background Using cellular phone among adults, teenagers and children has rapidly increased all over the world. Also, the concern on the possible health hazards of Electromagnetic Fields (EMF) induced from cell phones on reproduction has been growing in many countries. The aim was to assess the morphological parameters, survival rate and development of mouse in-vitro embryos obtained by natural ...

• Personal exposimeters are often used for RF-EMF measurements, but have shortcomings. We developed a novel on-body calibrated device with distributed sensors (BWDM). BWDM is designed to minimize body shielding and use frequency specific antennas. measured exposures in parallel three types of devices. Exposimeters provide slightly lower rank averaged accurately. Exposure radiofrequency electrom...

The expansion of network infrastructure in Greece has raised concerns about the possible negative health effects on sensitive groups, such as children, from exposure to long-term radiofrequency electromagnetic fields (RF-EMFs). objective this study is apply Unsupervised Machine Learning methods hierarchical clustering, order establish patterns EMF radiation schools. To end we performed measurem...

The prediction of the electric (E) field plays an important role in monitoring radiofrequency electromagnetic (RF-EMF) exposure induced by cellular networks. In this paper, we present approach to extrapolate E urban area using artificial neural network. We first apply a moving average method over sliding window out EMF random fluctuations and remove noise produced during drive test recording me...

Chronic diseases and illnesses associated with non-specific symptoms are on the rise. In addition to chronic stress in social and work environments, physical and chemical exposures at home, at work, and during leisure activities are causal or contributing environmental stressors that deserve attention by the general practitioner as well as by all other members of the health care community. It s...

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...

BACKGROUND Radio-frequency electromagnetic fields (RF EMF) of mobile communication systems are widespread in the living environment, yet their effects on humans are uncertain despite a growing body of literature. OBJECTIVES We investigated the influence of a Universal Mobile Telecommunications System (UMTS) base station-like signal on well-being and cognitive performance in subjects with and ...
