This animal study examined thornback ray embryos chronically exposed to alternating-current electromagnetic fields (1.8–4.6 μT) across embryogenesis (~20 weeks), relevant to subsea power cables. Exposed embryos showed higher activity levels than non-exposed embryos, while no differences were reported for development…

50 Hz Temporal Magnetic Field Monitoring from High-Voltage Power Lines: Sensor Design and Experimental Validation.

Research RF Safe Research Library Jan 1, 2024

This paper describes the design, calibration, and experimental validation of a low-cost tri-axial sensor for monitoring 50 Hz magnetic fields from high-voltage power lines. The sensor was calibrated on-board and in-lab against a narrowband EHP-50 benchmark and then verified in situ at two locations, with reported…

3D GIS for surface modelling of magnetic fields generated by overhead power lines and their validation in a complex urban area.

Research RF Safe Research Library Jan 1, 2021

This paper presents a 3D GIS approach to model magnetic fields from overhead high-voltage power lines while accounting for terrain relief and cable catenary. The model was validated against extensive field measurements in two complex urban environments and showed good agreement with measured values, though accuracy…

[Jurisprudence on occupational radiofrequency diseases].

Research RF Safe Research Library Jan 1, 2020

This article reviews Italian jurisprudence on alleged occupational tumours linked to RF EMF exposure (notably from wireless phones), with some cases also involving other RF sources or ELF magnetic fields. It contrasts court decisions that recognized occupational causation with others that rejected it, emphasizing how…

EXTREMELY LOW FREQUENCY ELECTROMAGNETIC FIELD EXPOSURE MEASUREMENT IN THE VICINITY OF WIND TURBINES.

Research RF Safe Research Library Jan 1, 2020

This exposure assessment measured extremely low frequency magnetic fields near 22 wind turbines in two wind farms in Greece using a Narda NBM-550 with an EHP-50F probe and processing aligned with the 2013/35/EU Directive. Mean magnetic field intensity at the turbine base was reported as low (0.146 µT) and declined to…

Analysis of personal and bedroom exposure to ELF-MFs in children in Italy and Switzerland.
