Exposure Variability Between 1- or 6-Minute and 30-Minute Averaging Time Lengths in Radiofrequency-Electromagnetic Field Exposure Monitoring

Research RF Safe Research Library Jan 1, 2025

This exposure assessment study compared RF-EMF measurements averaged over 1, 6, and 30 minutes using contiguous 1-minute data collected over 30 minutes at four indoor/outdoor sites across 15 frequency bands. Relative deviations between shorter averaging times and 30-minute averages were largely within ±3 dB. However,…

RF-EMF exposure in the transition to 5G: A multi-dimensional measurement campaign in the Peloponnese Region of Greece.

Research RF Safe Research Library Jan 1, 2025

This paper reports a year-long, frequency-selective RF-EMF measurement campaign (July 2023–June 2024) in the Peloponnese Region of Greece during the transition to 5G. The authors report that all measured electric field values were well below Greek safety limits, with the maximum ground-level value about 18× lower…

Modeling Radiofrequency Electromagnetic Field Wearable Distributed (Multi-Location) Measurements System for Evaluating Electromagnetic Hazards in the Work Environment.

Research RF Safe Research Library Jan 1, 2025

This engineering study modeled and tested a distributed wearable RF EMF measurement approach intended to reduce body-proximity effects on personal exposure meter readings. Numerical simulations covered 24 far-field wireless exposure scenarios (100–3600 MHz), and physical tests with three probes were also performed.…

Progress to Date on Cranial Electromagnetic Field Stimulation to Modulate Brain Activity.

Research RF Safe Research Library Jan 1, 2025

This prospective study enrolled 10 adults with atraumatic or traumatic brain injury who received tailored cranial EMF stimulation using a portable helmet with real-time EMF measurement and parameter adjustment. The abstract reports symptom resolution or remaining asymptomatic in 8 participants at varying stimulation…

Prospective cohort study on non-specific symptoms, cognitive, behavioral, sleep and mental health in relation to electronic media use and transportation noise among adolescents (HERMES): study protocol

Research RF Safe Research Library Jan 1, 2024

This protocol describes the third wave of the HERMES prospective adolescent cohort in Switzerland, with follow-up every four months and at one year. The study will assess electronic media use, modeled RF-EMF and transportation noise exposures, and a range of outcomes including cognition, behavior, sleep, mental…

Comparison of a radiofrequency electric and magnetic field source-based job-exposure matrix with personal radiofrequency exposure measurements.

Research RF Safe Research Library Jan 1, 2024

This study compared historical occupational RF-EMF exposure estimates from the INTEROCC RF job-exposure matrix (RF-JEM) with recent personal RF-EMF measurements from the OccRF-Health study in two countries. Agreement between the two approaches was poor for both exposure prevalence and 8-hour time-weighted average…

Personal exposure to radiofrequency electromagnetic fields in various occupations in Spain and France.

Research RF Safe Research Library Jan 1, 2023

This study conducted personal full-shift RF-EMF measurements in 333 workers across 46 occupations in Spain and France. Most 1-second measurements of electric and magnetic fields were below the device detection limit (≥1% of 1998 ICNIRP standards), though many workers had at least one detectable reading. A small…

[Electromagnetic field in the environment - estimation methods and monitoring].

Research RF Safe Research Library Jan 1, 2019

This paper discusses the legal context for environmental EMF measurements and describes methods for estimating EMF intensity from multiple sources, particularly cellular base stations. It presents an engineering concept for mobile EMF monitoring and reports verification testing of the measurement setup. Field…

Occupational exposure to electromagnetic fields. The situation in Greece.

Research RF Safe Research Library Jan 1, 2018

This exposure assessment study reports extensive EMF measurements and exposure mapping across multiple workplace settings in Greece in the context of implementing EU Directive 2013/35/EU. The authors report that most assessed workplaces did not exceed occupational limits, and often did not exceed general public…

Mitigation measures of electromagnetic field exposure in the vicinity of high frequency welders.

Research RF Safe Research Library Jan 1, 2017

This paper describes in situ EMF measurements around industrial high frequency (dielectric) welders, framed by Polish labor safety regulations aligned with EU Directive 2013/35/EU. It reports real-world scenarios where excessive EMF exposure can occur near welders, often linked to errors or omissions during…

Use of portable exposure meters for comparing mobile phone base station radiation in different types of areas in the cities of Basel and Amsterdam.

Research RF Safe Research Library Jan 1, 2014

This exposure assessment study used portable exposure meters to characterize variability and repeatability of mobile phone base station RF-EMF measurements in urban areas of Basel and Amsterdam. Reported exposure levels varied by area type and city, with downtown/business areas showing higher ranges than residential…
