STUDIES OF MICROWAVE ABSORPTION IN LIQUIDS BY PHASE FLUCTUATION OPTICAL HETERODYNE SPECTROSCOPY

Unknown authors · 1978

The method places a liquid sample in one arm of a Mach-Zender interferometer illuminated by a helium-neon laser and irradiates it with pulsed microwaves. Microwave absorption causes local thermal expansion that creates phase fluctuations in the laser beam, which are detected by heterodyning with a reference beam. The researchers plan to evaluate water, ethanediol, and other biologically significant liquids using a coaxial stub antenna and a miniature dielectric-loaded X-band waveguide. The technique offers very high sensitivity for detecting small temperature rises and produces no signal when there is no absorption.

CEREBROVASCULAR PERMEABILITY TO 14C-SUCROSE IN THE RAT FOLLOWING 2450 MHZ CW MICROWAVE IRRADIATION

Ohno, K., Pettigrew, K.D., Rapoport, S.I. · 1978

They measured cerebrovascular permeability-area products for 14C-sucrose in 5 brain regions. Mean PA values were similar across sham, 1 mW /cm², and 10 mW/cm² groups. The authors concluded that an effect of microwave treatment on barrier permeability cannot be concluded.

The Performance of a New Direct Contact Applicator for Microwave Diathermy

Gideon Kantor, Donald M. Witters, Jr., John W. Greiser · 1978

Researchers evaluated a direct contact applicator for microwave diathermy at 2.45 GHz by studying near-field patterns, thermographic heating patterns in fat and muscle phantoms, and leakage radiation. The applicator used a circular waveguide with a conical flare horn, annular choke, and dual posts to generate circular polarization. Heating patterns on muscle phantoms and inside fat-muscle phantoms were spatially similar and relatively uniform. Leakage was 0.8 mW/cm² per 100 W forward power for direct contact and 4 mW/cm² per 100 W for a 1-cm air gap, with +2 dB uncertainty. The study concluded the applicator is technically feasible, safe, effective, and a viable candidate for hyperthermia.

Health Aspects of Exposure to Microwave and Radio Frequency Radiation

M. Repacholi · 1978

Descriptions are given on the physical characteristics, biophysical principles, and biological effects of exposure to these radiations. Public and occupational health implications and protective measures against the hazards of exposure are also described. Existing standards for general public and occupational exposure have been tabulated and described to inform the reader about presently accepted maximum permitted exposure levels.

Risks associated with the utilization of non ionizing radiations

R. MARCHAND · 1978

The congress theme was chosen because rapid growth in medical, industrial, and domestic uses of non-ionizing radiations, especially microwaves and lasers, required better knowledge of their possible effects on people. Papers were to cover specific effects of short or long-term exposures, indirect effects, safety standards, measurement methods, protection measures, and surveillance. Authors had to submit six copies of an abstract by December 1, 1977, and if accepted, send an original manuscript and three copies by February 15, 1978.

MEASURED PATTERNS OF STRAY RADIATION PRODUCED BY THERAPEUTIC MICROWAVE APPLICATORS WHEN APPLIED TO TISSUE-SUBSTITUTE MODELS AND HUMAN SUBJECTS

Lehmann et al. · 1978

Researchers measured stray radiation patterns from two prototype diathermy applicators applied to four tissue-substitute models and four human subjects. The applicators were placed at eight anatomical sites on the human subjects. Measured power-density levels showed that neither applicator would comply with the proposed Bureau of Radiological Health microwave diathermy performance standard. Leakage levels depended on applicator orientation, tissue model, subject size, and anatomical site. Good contact between the applicator and the model or subject reduced stray radiation, while poor contact increased it.
