EVIDENCE OF NEUROPATHOLOGY IN CHRONICALLY IRRADIATED HAMSTERS BY 2450 MHz MICROWAVES AT 10mW/cm2

Albert, E.N., DeSantis, M. · 1976

Adult Chinese hamsters were exposed to 2450 MHz microwaves at 10 and 25 mw/cm² for 14 hours per day over 20 days. At 10 mw/cm² some experimental animals had fewer dendritic spines, axonal swelling, axonal beading, hyperchromatic neurons, and cytoplasmic swelling of neurons, with no gliosis, hemorrhage, or pyknosis. The investigators considered the observed morphological changes probably reversible, although no recovery studies were performed. At 25 mw/cm² similar histological alterations occurred, with some evidence of quantitatively greater effects, and animals were more irritable during the first 7-14 days but appeared to become acclimatized.

Microwave Applications in the Food Industry

G. Faillon, E. Maloney · 1976

The study describes two new food-industry applications of microwave power: roasting cocoa beans in Europe and drying egg-volk paste in Japan. Microwave roasting of cocoa beans proved highly effective and produced beans judged clearly superior to conventional methods. Microwave drying of egg-volk paste was found feasible and the product considered superior in characteristics to conventionally produced powder.

RESEARCH ON THE POSSIBLE USE OF MICROWAVES IN PLASTER INDUSTRY

A. Priou, C. Fournet-Fayas, J. C. Gellardin · 1976

The study tested microwave drying using plaster bars placed in a waveguide. Water loss was recorded continuously via a balance and constraint gauge bridge with 0.5 g sensitivity. Tests were conducted at 2450 MHz = 50 MHz, power between 8 W and 200 W, with air at 6 m/s and 75°C, and results were compared with oven drying at 45°C.

A New Self-Balancing DC-Substitution RF Power Meter

Neil T. Larsen · 1976

Researchers developed a new DC-substitution RF power meter that is not a form of Wheatstone bridge. The instrument allows four-terminal measurement of bolometer resistance and provides improved accuracy and lower noise at lower cost. Servo system measurement errors are typically less than 0.01 percent. Performance testing showed a standard deviation of about 0.008 percent over 1024 random measurements.

Microwave Irradiation Induced Decreased Binding of Atropine and Acetylcholine to an Acetylcholine Receptor Rich Fraction of Whole Rat Brain Homogenate

Unknown authors · 1976

Researchers used whole brain homogenate from unsexed adult Sprague-Dawley rats. For atropine, the bound-to-free ratio fell from near 2 in controls to near 1 in irradiated samples. For acetylcholine, irradiated samples showed a tendency toward lower ratios, but insufficient data prevented a significance test.

HIGH POWER RADIOFREQUENCY AND MICROWAVE RADIATION SOURCES: A STUDY OF RELATIVE ENVIRONMENTAL SIGNIFICANCE

Norbert N. Hankin et al. · 1976

Researchers analyzed environmental radiofrequency and microwave radiation from high-power sources including satellite communication earth terminals, radars, and broadcast transmitters. Considering factors such as number of sources, potentially exposed persons, and operating procedures, they concluded broadcast transmitters constitute the most environmentally significant source category. For non-occupational individuals at closest approach distances, anticipated power densities were generally below the 10 mW/cm² occupational threshold. Radar time-averaged power densities were two to four orders of magnitude below peak values due to pulsing, and rotating antennas reduced exposure further.

THE SLEEP PROCESS OF RABBITS EXPOSED TO LOW INTENSITY NON-IONIZING ELECTROMAGNETIC RADIATION. I. DEVELOPMENT OF METHODOLOGY

Robert C. Manthei, Zorach R. Glaser · 1976

Eight adult male Dutch rabbits received daily 2-hour exposures to pulsed 3.7 GHz microwaves at 10 mW/cm² for 60 days while chronic ECoG, EOG, and EMG recordings were made on a 24-hour basis. The implant assembly allowed chronic post-irradiation recording with no metallic elements on the animals during microwave exposure. Logic circuitry quantified the frequency and duration of paradoxical sleep episodes. Preliminary data from control rabbits showed paradoxical sleep occupied 25-35 minutes of total sleep time in 3-8 minute segments across 16-hour recordings. The authors reported it was too early to determine whether microwave exposure affected paradoxical sleep.

An upper bound on coefficient of transmission of microwave leakage into biological tissues

Kamal AA, Al-Badwaihy K, Hashish E · 1976

Researchers modeled microwave transmission into a planar half-space of biological tissue using elementary electric and magnetic dipoles as sources. They computed the transmission coefficient U for four dipole configurations and found that its maximum value increases and shifts toward the dipole projection as the dipole height decreases. The authors state that near-zone fields may be hazardous even below current standard safe levels because they can have higher transmission coefficients than assumed plane-wave exposures.
