Melatonin and omega-3 neuroprotection in prenatal rat spinal cord exposed to 900 MHz electromagnetic field.

Research RF Safe Research Library Jan 1, 2025

This animal study examined prenatal 900 MHz EMF exposure (2 hours/day for 21 days) in pregnant rats and assessed spinal cord outcomes in male offspring at postnatal day 35. Volume-based stereological measures (GM/WM ratios and total spinal cord volume) did not differ significantly between groups. Microscopy reported…

Improved assessment of radiofrequency electromagnetic field power deposition near orthopaedic device using a bone-inclusive ASTM phantom under 1.5T and 3T MRI.

Research RF Safe Research Library Jan 1, 2024

This engineering/simulation study proposes a bone-inclusive ASTM phantom to improve assessment of RF power deposition near orthopaedic implants during 1.5 T and 3 T MRI. Using numerical simulations across multiple implant families, the authors report better correlation of peak 1 g SAR near implants with anatomically…

Comparison of radiofrequency electromagnetic field exposure levels in different everyday microenvironments in an international context.

Research RF Safe Research Library Jan 1, 2018

This exposure assessment quantified RF-EMF levels using portable, high-sampling-rate devices across 94 outdoor microenvironments and 18 public transport vehicles in six countries. Mean outdoor exposure ranged from 0.23 to 1.85 V/m, and public transport exposure ranged from 0.32 to 0.86 V/m. Exposure varied…

Neurodegenerative disease and magnetic field exposure in UK electricity supply workers

Research RF Safe Research Library Jan 1, 2014

This cohort study examined mortality from Alzheimer’s disease, motor neurone disease, and Parkinson’s disease among 73,051 UK electricity supply workers from 1973 to 2010. Occupational magnetic-field exposure was assessed using detailed calculations and analyzed using Poisson regression across lifetime, distant…

Effect of sputtering power on structural and optical properties of radio frequency-sputtered In2S3 thin films.

Research RF Safe Research Library Jan 1, 2014

This engineering/materials study examined how RF magnetron sputtering power affects the structural and optical properties of In2S3 thin films intended as a CdS buffer substitute in CIGS solar cells. Films deposited at 60–120 W were characterized using XRD, AFM, EDS, and UV-visible spectrophotometry. The films were…

Ultrafast volumetric B1 (+) mapping for improved radiofrequency shimming in 3 tesla body MRI.

Research RF Safe Research Library Jan 1, 2014

This engineering/clinical MRI methods study evaluated ultrafast volumetric DREAM B1+ mapping to refine patient-adaptive RF shimming at 3T. In 20 patients and three volunteers, a multi-slice adaptive RF shimming approach reduced flip-angle deviations and improved B1+ homogeneity compared with central-slice-based…

Radiofrequency waves with filling and peeling substances: An innovative minimally invasive technique for facial rejuvenation.

Research RF Safe Research Library Jan 1, 2011

This pivotal clinical trial describes a minimally invasive facial rejuvenation procedure combining fillers, biorevitalization, peeling, and intradermal radiofrequency delivered by the Spherofill Medical Plus device. In 112 patients divided into five groups, GAIS scores showed statistically significant improvement…
