Jan 1, 2008
This review describes public concerns and scientific reports of non-thermal biological effects from low-intensity ELF and RF exposures. It lists multiple health endpoints reported to be associated with ELF and/or RF and highlights the BioInitiative Report’s conclusion that a reasonable suspicion of risk exists at…
Head-to-head comparison of coronary plaque evaluation between multislice computed tomography and intravascular ultrasound radiofrequency data analysis.

Jan 1, 2008
This study compared coronary plaque assessment by 64-slice multislice computed tomography (MSCT) with virtual histology intravascular ultrasound (VH IVUS) in 50 patients. The Agatston score on MSCT correlated moderately with calcium volume measured by VH IVUS, and MSCT plaque categories broadly reflected differences…
SAR changes in a human head model for plane wave exposure (500 - 2500 MHz) and a comparison with IEEE 2005 safety limits.

Jan 1, 2008
This engineering/modeling study derived external electric field values from peak average 10 g SAR in a realistic human head model exposed to plane waves at 500–2500 MHz. The derived fields were compared with IEEE and ICNIRP reference levels across multiple incident directions and polarizations. The authors report…

Jan 1, 2008
This conference paper reports early development of a cell phone-based video streaming system to deliver video reminders for people with early dementia. Carers can record and schedule reminders remotely via a computer and webcam. A first prototype was implemented, with an initial field trial scheduled and a larger…
Radiofrequency dosimetry in subjects implanted with metallic straight wires: a numerical study.
Research
RF Safe Research Library
Jan 1, 2008
This numerical FDTD study modeled RF exposure at 900 and 1800 MHz in tissue containing thin metallic straight wire implants. The model indicates that the wire can substantially increase local SAR, creating high SAR gradients. Despite this, the authors report that exposures below current safe levels resulted in…
[Measurements of professional exposure to ELF fields in some production areas within the territory of Regione Campania and comparison with the action values according to 2004/40/CE Directive].

Jan 1, 2007
This occupational exposure assessment measured ELF magnetic fields in 400 workers across 80 work areas in several production sectors in Regione Campania. Measurements were taken continuously over two shifts and processed into RMS magnetic-field values. The authors report no exceedance of the EU 2004/40/CE action…
[ELF-MF occupational exposure: repeated measures on workers].
Research

Jan 1, 2007
This occupational exposure assessment used personal dosimeters to estimate ELF magnetic field exposure in 543 workers across 9 occupational settings in Emilia-Romagna. Median time-weighted average exposure was 0.14 microT, with tile production showing the highest setting-level TWA. Repeat measurements after 6–9…
[Evaluation of the genotoxicity of the extremely low frequency-magnetic fields (ELF-MF) in workers exposed for professional reasons].

Jan 1, 2007
This occupational study assessed whether extremely low frequency magnetic fields (ELF-MF) are associated with genotoxicity using cytogenetic assays in 109 workers. Comparisons across exposure strata, including a highest-exposed subgroup (TWA > 1 microT), found no significant differences in CA, SCE, or MN outcomes.…
Use of radiofrequency hepatic parenchymal transection device in hepatic hemangioma resection: early experience and lessons learned.

Jan 1, 2007
This retrospective case series reviewed four resections of symptomatic giant cavernous hepatic hemangiomas using an RF-powered multiarray (Habib sealer) for hepatic parenchymal transection. No blood transfusions were required and no major biliary or vascular injuries were observed at 1-year follow-up; one…
Comparison of the effects of continuous and pulsed mobile phone like RF exposure on the human EEG.

Jan 1, 2007
This study tested whether GSM-like RF exposure affects resting human EEG, focusing on alpha band power and non-linear EEG features. Using a fully counterbalanced cross-over design with 12 participants and a dipole antenna intended to better resemble handset exposure, the authors found no changes after 15 minutes of…
Chaotic mixing induced by a magnetic chain in a rotating magnetic field.
Research
RF Safe Research Library
Jan 1, 2007
This paper studies chaotic mixing driven by breakup and reformation of a magnetic particle chain under a rotating magnetic field using direct numerical simulation. The authors report that chain motion and the degree of chaos depend strongly on the Mason number, and that a limited Mason number range produces repeated…
Charge and current neutralization of an ion-beam pulse propagating in a background plasma along a solenoidal magnetic field.

This paper reports analytical theory on how a small solenoidal magnetic field affects an ion-beam pulse propagating through background plasma. The authors predict enhanced self-electric and self-magnetic fields under a resonance-like condition (omegace ≈ omegape beta_b) attributed to a dynamo effect. The combined…

Jan 1, 2000
This review argues that current mobile-telephony safety guidelines address excessive microwave heating but may not account for potential non-thermal influences of low-intensity, pulsed radiation. It highlights an asserted oscillatory similarity between pulsed microwave signals and certain electrochemical activities…
