Operator Exposure to Radiofrequency Fields Near a Hyperthermia Device

Health Physics, 1983
Radiofrequency-induced hyperthermia has recently gained acceptance in cancer therapy. One of a few commercially available systems is the Magnetrode, a device operating at 13.56 MHz with an output power up to 1000 W. Heating of the prescribed part of the patient's body is accomplished by one of the coil electrodes.

Setting Exposure Limits for Radiofrequency Radiation and Microwaves in China

Reviews on Environmental Health, 1994
This review presents Chinese ELVs for radiofrequency radiation and microwaves. The ELVs were based on thermal or on non-thermal effects.

Exposure Survey of Operators of Radiofrequency Dielectric Heaters in Australia

Health Physics, 1986
A survey of industrial radiofrequency (RF) dielectric heaters within Australia was carried out during 1982 and 1983. The heaters operated within the frequency range 11-50 MHz and had available RF powers between 0.5 and 70 kW. The electric and magnetic field strengths in the vicinity of the operators of 101 heaters were surveyed.

OCCUPATIONAL EXPOSURE OF NMR SPECTROMETRISTS TO STATIC AND RADIOFREQUENCY FIELDS

Radiation Protection Dosimetry, 2017
Occupational exposure to static and radiofrequency fields emitted by nuclear magnetic resonance spectrometers was assessed through systematic field metering during operation of 19 devices in nine research centers. Whereas no measurable levels of radiofrequency radiation were registered outside the spectrometers, significant exposure to static field was

Radiofrequency portable transmitters exposure

2014
Several activities, in particular serviceman, require the use of a portable transmitter. These portable transmitters can emit several Watts in the VHF frequency band. These devices are worn near the body and there are questioning on the level of the exposure to the electromagnetic field which they get.

A practical method to evaluate radiofrequency exposure of mast workers

Radiation Protection Dosimetry, 2008
Assessment of occupational exposure to radiofrequency (RF) fields in telecommunication transmitter masts is a challenging task. For conventional field strength measurements using manually operated instruments, it is difficult to document the locations of measurements while climbing up a mast. Logging RF dosemeters worn by the workers, on the other hand,

Radiofrequency exposure and mammalian cell toxicity, genotoxicity, and transformation

Bioelectromagnetics, 2003
The published in vitro literature relevant to the issue of the possible induction of toxicity, genotoxicity, and transformation of mammalian cells due to radiofrequency field (RF) exposure is examined. In some instances, information about related in vivo studies is presented.

Exposure Guidelines for Radiofrequency Electromagnetic Fields

1999
In January 1997 the Health Council of the Netherlands published an advisory report1 on the health effects of exposure to radiofrequency electromagnetic fields and radiation. In this report, a committee of the Health Council proposes exposure guidelines on the basis of the available scientific literature, taking existing guidelines into consideration ...
