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.

NUMERICAL STUDIES OF ABSORPTION OF ELECTROMAGNETIC ENERGY BY MAN

Mark Joseph Hagmann · 1978

The study established convergence criteria for moment-method solutions in electromagnetics. New procedures were developed to improve convergence in two-dimensional and three-dimensional problems. Ground, reflector, and multibody effects were treated numerically with human models for the first time.

Head resonance--Numerical solutions and experimental results

Hagmann J, Gandhi OP, D'Andrea JA, Chatterjee I · 1978

Researchers previously reported numerical solutions for a realistic model of man showing resonance of the intact human head at about 350 MHz. At head resonance, the absorption cross section for the head region is 3.0 times the physical cross section. Head resonance for the laboratory rat occurs near 2450 MHz.

AFOSH STANDARD 161-9 - OCCUPATIONAL HEALTH - EXPOSURE TO RADIOFREQUENCY RADIATION

Unknown authors · 1978

It applies to military and civilian personnel at Air Force facilities worldwide and addresses protection of nonoccupationally exposed personnel from Air Force-owned sources. Warning signs are required where access to power density levels exceeding the PEL is probable.

A Review of Microwave Oven Safety

J. M. Osepchuk · 1978

The review examines microwave oven leakage from ovens manufactured to meet government emission standards. Typical leakage values imply exposure well below the most conservative exposure standards worldwide. Field survey data indicate the overwhelming majority of certified ovens show leakage well below permissible limits, with increasing certainty over time. The review concludes that microwave ovens are as safe as in 1973 and accepted as safe under equivalent emission regulations in various countries including Eastern Europe.

Heating of Biological Tissue in the Induction Field of VHF Portable Radio Transmitters

Quirino Balzano, Oscar Garay, Frances R. Steel · 1978

Researchers built two phantom models to study heating of simulated human tissue from VHF portable radio antennas. Temperature measurements showed penetrating power densities in the tissue were substantially lower than expected from an incident plane wave with the same electric field intensity. In the head phantom, a 6-W radio held 0.2 inches from the mouth caused less than 0.1°C temperature rise in one minute. The maximum power density penetrating the dummy was less than 1 mW/cm² at the middle forehead, and no detectable temperature increase occurred near the eyes.

CONSIDERATIONS AND CRITERIA FOR A RECOMMENDED STANDARD FOR OCCUPATIONAL EXPOSURE TO RADIOFREQUENCY AND MICROWAVE FIELDS

Unknown authors · 1978

The criteria document was scheduled for completion by August 1979. Preparation involved NIOSH research, literature review, stakeholder communication, plant visits, and expert review. Recommendations were based on critical evaluation of biological effects and epidemiological data, plus instrumentation, engineering controls, work practices, and medical monitoring. Over 300 letters were sent to manufacturers, users, trade associations, and organized labor, yielding approximately 70 responses.
