Adverse effects of excessive mobile phone use.

Research RF Safe Research Library Jan 1, 2008

This cross-sectional questionnaire study surveyed 286 medical students about mobile phone use and health complaints. The abstract reports multiple self-reported symptoms (including impaired concentration, memory disturbances, sleeplessness, fatigue, and headache) and notes that 44.4% of respondents attributed their…

The effect of MRET polymer compound on SAR values of RF phones.

Research RF Safe Research Library Jan 1, 2008

This article describes a hypothesis and experimental testing of an MRET polymer compound applied to RF phones. It reports increased dielectric permittivity in water-based solutions and reduced SAR values in a tissue-simulating phantom head. It also reports no significant change in air measurements of phone signals,…

New functions developed for ICU/CCU remote monitoring system using a 3G mobile phone and evaluations of the system.

Research RF Safe Research Library Jan 1, 2008

This conference paper describes development of new functions for an ICU/CCU remote monitoring system that uses a 3G mobile phone. The authors state that evaluations were performed on several different mobile phones and suggest the system has accuracy and real-time performance suitable for hospital adoption. The…

Chemotherapy side-effect management using mobile phones.

Research RF Safe Research Library Jan 1, 2008

This conference paper describes a mobile-phone telemedicine system for managing chemotherapy side-effects at home using symptom diaries and automated alerts to nurses. Six patients used the system for two cycles of oral chemotherapy. The abstract reports two instances where moderate symptoms deteriorated to more…

Electromagnetic interference to infusion pumps. Update2008 from GSM mobile phones.

Research RF Safe Research Library Jan 1, 2008

This engineering study updates a prior (2005) survey on electromagnetic interference (EMI) affecting infusion pumps and extends testing to DECT phones and WiFi terminals. It reports a reduced failure rate for GSM phone exposure compared with 2005 (58% to 30%). The authors report that WiFi and DECT did not pose a real…

Single access point localisation for wearable wireless sensors.

Research RF Safe Research Library Jan 1, 2008

This engineering conference paper describes a single access point method for localizing a subject using RF signals from wearable wireless sensors. The approach combines RSSI and LQI measurements from one basestation and applies filtering. The abstract reports that accuracy can approach that of multi-basestation…

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…

Ultrastructural alterations and occurrence of apoptosis in developing follicles exposed to low frequency electromagnetic field in rat ovary.

Research RF Safe Research Library Jan 1, 2007

This animal study examined rat ovaries after chronic exposure to a 3 mT low-frequency electromagnetic field for 4 hours per day over 4 months. Using TEM and TUNEL, the authors report ultrastructural alterations in oocytes and more frequent apoptosis-associated changes in granulosa and corona radiata cells versus…

Effects of electromagnetic field produced by mobile phones on the oxidant and antioxidant status of rats.

Research RF Safe Research Library Jan 1, 2007

This rat study examined whether EMR from GSM mobile phones affects oxidant/antioxidant status. Compared with controls, exposed rats had lower plasma antioxidant vitamins (C, E, A), reduced glutathione, and lower CAT and SOD activities. The acute exposure condition was reported to produce larger decreases than the…

[Operational aspects of risk perception in the electromagnetic fields exposition].

Research RF Safe Research Library Jan 1, 2007

This study reports on symptomatology and risk perception among 45 people living near power-lines in the Benevento area. Although measured electric and magnetic fields were described as being within the normal range, participants reported symptoms mainly in subjective and behavioural domains. The authors argue that…

Biophoton emission of MDCK cell with hydrogen peroxide and 60 Hz AC magnetic field.

Research RF Safe Research Library Jan 1, 2007

This in vitro study measured biophoton/chemiluminescence emission from MDCK cells after inducing reactive oxygen species with hydrogen peroxide. The authors report that photon emission increased with hydrogen peroxide dose and that photomultiplier tube measurements agreed with fluorescence microscopy observations.…

Evaluation of mulitprobe radiofrequency technology in a porcine model.

Research RF Safe Research Library Jan 1, 2007

This animal study evaluated two multiprobe radiofrequency ablation device approaches in pigs, including an impedance-based algorithm and clustered/combination probes with and without a switcher controller. The Pringle maneuver was associated with larger ablation volumes and shorter ablation times in one experiment,…

AC electric field-induced alignment and long-range assembly of multi-wall carbon nanotubes inside aqueous media.

Research RF Safe Research Library Jan 1, 2007

This engineering study examines multi-wall carbon nanotubes suspended in water exposed to AC electric fields generated by 3D electrodes. It reports field-induced polarization leading to nanotube alignment and long-range, electrically conducting assemblies spanning the electrode gap, with assembly length controlled by…

A mobile clinical e-portfolio for nursing and medical students, using wireless personal digital assistants (PDAs).

Research RF Safe Research Library Jan 1, 2006

This paper outlines the development and evaluation of a wireless PDA-based clinical e-portfolio intended to support reflective clinical learning. The tool synchronized wirelessly via cellular signal or Wi-Fi to a web-based portfolio. An evaluation with nurse practitioner and medical students reported positive…

The Effectiveness of a Conductive Patch and a Conductive Bed Pad in Reducing Induced Human Body Voltage Via the Application of Earth Ground

Research RF Safe Research Library Jan 1, 2005

This engineering-style study measured voltage induced on the human body via capacitive coupling to the environment using a high-impedance measurement head. It then applied earth grounding through a conductive patch and a conductive bed pad. Both grounding methods reportedly reduced coupled 60 Hz mains voltage by at…

Physics and biology of mobile telephony

Research RF Safe Research Library 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…

Headaches from cellular telephones: are they real and what are the implications?

Research RF Safe Research Library Mar 1, 1998

This review discusses reports of headaches occurring with hand-held cellular telephone use and argues they are likely real and attributable to telephone emissions. It points to earlier reports of headaches from low-intensity microwave exposure and proposes biological plausibility via effects on the blood-brain…
