DIELECTRIC PARAMETERS OF HUMAN BLOOD SERUM IN THE RANGE 1-30 Mc/s

V. A. Konovalenko, V. A. Yamshanov · 1971

Researchers measured the complex dielectric constant of water, NaCl solutions, serum from healthy donors, a cancer patient, and horse serum over 1-30 Mc/s. Serum from three healthy donors, one cancer patient, and preserved horse serum showed practically identical dielectric parameters within measurement error. The real part of the complex dielectric constant of native serum matched that of 0.1 N NaCl across the whole range, indicating salts determine this component. Dialysis of serum against 0.01 N NaCl reduced salt concentration so that the reactive component matched water while the active conductivity exceeded the salt solution, an excess attributable to proteins.

Microwave Cataract

Robert W. Neidlinger · 1971

The author reviews at least four main mechanisms by which microwave radiation could produce cataracts. The author notes that it is extremely difficult to design experiments that yield unequivocal results relevant to occupational exposure.

Induced fields and heating within a cranial structure irradiated by an electromagnetic plane wave

Shapiro AR, Lutomirski RF, Yura HT · 1971

Researchers calculated induced fields and static heating patterns for a multilayered spherical model of a primate cranial structure irradiated by a plane wave at 3000 MHz. They demonstrated that the semi-infinite slab model is inappropriate for calculating microwave radiation dosage for the human head and that the infinite slab model can give large errors for the internal fields.

Microwave Heating of Simulated Human Limbs by Aperture Sources

Henry S. Ho et al. · 1971

The study used triple-layered dielectric cylinders to simulate human fat, muscle, and bone in thigh and arm models. Theoretical calculations covered frequencies from 433 to 2450 MHz using a cylindrical wave summation method on a high-speed computer. An experimental aperture source at 918 MHz was built and temperature patterns were recorded with a thermograph camera. Theoretical and experimental results showed agreement. The methods may be applied to designing applicators for therapeutic tissue heating.

ELECTROMAGNETIC RADIATION INTERFERENCE with CARDIAC PACEMAKERS

Paul S. Ruggera, Robert L. Elder · 1971

The report explains how pacemakers and microwave ovens function and describes the mechanism of electromagnetic interference. Synchronous pacemakers are more susceptible to electromagnetic interference than asynchronous models because of their low-level energy-sensing circuits. The federal standard limits microwave oven leakage to 1 mW/cm2 at 5 cm from the surface initially, allowing up to 5 mW/cm2 over the oven's life. At the standard's maximum leakage, a power density of 5.4 muW/cm2 would exist 5 feet from the oven assuming 50 percent body absorption.

M. DEROCHE · 1971

No progressive diseases linked to the exposure were found. Reversible functional disturbances including fatigue, headaches, insomnia, muscle cramps, and memory difficulties were identified. Clinical tests on 17 technicians in Rennes showed normal blood pressure, blood sugar, sedimentation rate, blood count, and EEG except minor unexplained variations on three traces. Field measurements at the Metz-Luttange transmitter showed levels from 0.001 to 2.22 mW/cm² in personnel areas.

Acute effects involve short-term action of high inte while chronic effects involve action of low-intensity microw. Case histories document chronic disease progression after contact with UHF fields. The monograph concludes with organizational and technical preventive measures. The review notes shortcomings including an unresolved distinction between thermal and nonthermal mechanisms.

ELECTRICAL IMPEDANCE OF THE HUMAN BODY FOR HF (2-30 MHz) BAND (INITIAL RESULTS)

R. W. Carson, W. E. Innis · 1970

Researchers measured hand-to-hand RF impedance in 16 individuals across the 2 to 30 MHz range using a vector impedance meter with copper tube electrodes. The real part of impedance was approximately the same for all individuals at each frequency, decreasing from about 760 ohms at 2 MHz to about 133 ohms at 30 MHz. These experimental values agreed well with a prior theoretical study. The real part followed an approximately negative exponential pattern across the frequency range.
