Analysis of Human Exposure to Electric and Magnetic Fields While Charging and Driving an Electric Vehicle

Research RF Safe Research Library Jan 1, 2025

This paper describes planned experimental measurements of electric and magnetic fields generated by electric vehicles during charging and driving. The abstract emphasizes that occupants can experience notable EMF exposure due to proximity to vehicle electrical systems, while stating that specific health risks in the…

Greater prevalence of symptoms associated with higher exposures to mobile phone base stations in a hilly, densely populated city in Mizoram, India

Research RF Safe Research Library Jan 1, 2025

This cross-sectional study compared 183 higher-exposed residents with 126 matched reference residents and assessed symptoms via questionnaire alongside in-home RF-EMF power density measurements from mobile phone base stations. Higher exposure (including proximity within 50 m and power densities of 5–8 mW/m2) was…

Impact of magnetic fields from tablets, laptops, smartphones, and household/leisure magnets on cardiac implantable electronic devices

Research RF Safe Research Library Jan 1, 2025

This study tested magnetic fields from tablets, laptops, smartphones, and household/leisure magnets against 13 cardiac implantable electronic device (CIED) models to assess magnet mode activation. It reports that these consumer devices can trigger magnet mode when in close proximity, with median activation distances…

Residential exposure to magnetic field due to high-voltage power lines and childhood leukemia risk in mainland France - GEOCAP case-control study

Research RF Safe Research Library Jan 1, 2025

This French GEOCAP registry-based case-control study evaluated childhood acute leukemia risk in relation to residential proximity to high-voltage overhead power lines and modeled ELF magnetic-field exposure. It reports an increased risk for children under 5 living within 50 m of power lines, particularly when…

Use of Electrical Household Appliances and Risk of All Types of Tumours: A Case-Control Study

Research RF Safe Research Library Jan 1, 2025

This multi-hospital case-control study (n=316) examined associations between use of common household electrical appliances emitting ELF EMF and tumour risk. Most devices showed below-unity odds ratios, while computer screen and microwave oven use showed slightly increased odds with wide confidence intervals.…

The Effect of Proximity Sensor & Grip Sensor Use on Specific Absorption Rate (SAR) in Smartphones

Research RF Safe Research Library Jan 1, 2025

This engineering study examined how smartphone proximity and grip sensors affect SAR during LTE and 5G NR operation in a 3D measurement environment. The abstract reports that enabling these sensors reduces SAR relative to being turned off, with reductions varying by sensor and frequency. The authors attribute the…

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

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.…

A Decision Support System for Managing Health Symptoms of Living Near Mobile Phone Base Stations

Research RF Safe Research Library Jan 1, 2024

This analytical study evaluated machine learning models (SVM and Random Forest) to predict health symptoms in adults living near mobile phone base stations. The SVM model reportedly achieved high predictive performance for headache, sleep disturbance, dizziness, vertigo, and fatigue, and outperformed Random Forest…

Risk factors of congenital anomalies of the kidney and urinary tract (CAKUT): Exposure to mobile phones during pregnancy.

Research RF Safe Research Library Jan 1, 2024

This case-control study (57 CAKUT cases, 57 controls) evaluated multiple risk factors for CAKUT, including mobile phone-related EMF exposure during pregnancy. Longer maternal daily call time and higher effective SAR (SAR × call time) were reported to be associated with increased CAKUT risk, while phone proximity when…

An Evaluation of Electromagnetic Exposure While Using Ultra-High Frequency Radiofrequency Identification (UHF RFID) Guns.

Research RF Safe Research Library Jan 1, 2019

This study simulated SAR from handheld UHF RFID readers (“RFID guns”) in adult male and female models across seven close-proximity scenarios involving an operator, scanned person, or bystander. SAR was reported to comply with general public limits at emissions up to 1 W, but higher-power devices (>2 W, and especially…
