DEVELOPMENT OF OCCUPATIONAL EXPOSURE RECOMMENDATIONS: OBSERVATIONS ON THE USES OF RF/MICROWAVE ENERGY

National Institute for Occupational Safety and Health et al. · 1978

NIOSH mailed more than 300 contact letters in July 1978 to manufacturers, users, trade associations, professional societies, and labor unions. The letters requested information on bioeffects studies, engineering controls, medical monitoring, protective devices, measurement techniques, work practices, recordkeeping, and warning devices. The Summary Plant Observation Report prepared in March 1979 was incorporated into the draft criteria document chapters on environmental data and engineering controls and on work practices.

THE DESIGN AND PERFORMANCE OF A CIRCULARLY POLARIZED DIRECT CONTACT APPLICATOR FOR MICROWAVE DIATHERMY

G. Kantor, D. M. Witters, J. W. Greiser · 1977

The applicator operates at 2.45 GHz with a 15.2 cm diameter and can handle up to 300 Watts of input power. It uses a microwave choke around the aperture to suppress leakage and a resistive card at the horn's back to minimize mismatch when applied to tissue. Impedance matching tests gave a VSWR below 2.1 for four back positions and free space.

NEW TYPES OF MICROWAVE DIATHERMY APPLICATORS -- COMPARISON OF PERFORMANCE WITH CONVENTIONAL TYPES

G. Kantor · 1977

Researchers compared heating patterns of new direct contact applicators with conventional spaced applicators using planar phantoms of simulated fat and muscle tissue. The direct contact applicators provided more uniform heating than the spaced applicators. Leakage radiation for a commercial direct contact applicator was measured at less than 5 mW/cm² per 100 W at 5 cm spacing. Scattered field levels for loaded applicators were typically 20 mW/cm² per 100 W at 13 cm distance.

BIOTELEMETRY ANTENNAS IN BIOMECHANICS: THE PROBLEM OF SMALL BODY-MOUNTED ANTENNAS

NEUKOMM Peter A. · 1977

Maximum transmission loss increased from 20 to 30 dB as frequency rose from 200 to 1000 MHz at a 35 mm distance, and from 17 to 24 dB at a 77 mm distance over the same frequency range. The study concluded that ideal telemetry frequencies lie within 75-150 MHz, where losses stay below 18 dB at 35 mm and below 14 dB at 77 mm antenna-trunk distance. The flat helical dipole was recommended as the best antenna for biomechanics telemetry because varying body distance does not detune it out of its bandwidth.
