Operator exposure to radiofrequency fields near a hyperthermia device.
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. To assess exposure to the operator of the device, the intensities of the electric and magnetic fields in the vicinity of three Magnetrode coils were measured, while a human phantom or a human being was in the coil. Exposure to the device operator is compared with the recommendations of the Canadian safety code and the recent ANSI recommendations.
