REGIONAL LEVELS OF CYCLIC AMP IN RAT BRAIN: PITFALLS OF MICROWAVE INACTIVATION

R. H. Lenox, J. L. Meyerhoff, O. P. Gandhi, H. L. Wray · 1977

Researchers varied microwave exposure configuration and output power to inactivate brain enzymes in rats. They studied the rate of metabolic inactivation in various brain regions by measuring cyclic AMP and phosphodiesterase activity. Exposure times needed to stabilize cyclic AMP levels differed among the hypothalamus, cortex, and cerebellum. Cyclic AMP levels in some regions decreased when inactivation was more rapid.

Trends in Nonionizing Electromagnetic Radiation Bioeffects Research and Related Occupational Health Aspects

C. H. Dodge, Z. R. Glaser · 1977

The authors selectively reviewed international literature from circa 1970 to 1977 on biological and clinical phenomena associated with microwave or radiofrequency electromagnetic field exposure. The review concluded that mechanisms of EM field bioeffects were becoming better understood as investigative technology and methodology improved. Recent Western evidence supported Soviet and European claims that EM fields can affect nervous system function and morphology in small mammals, birds, and invertebrates at power levels below those defined as thermogenic in the West. Clinical studies in the West did not corroborate Soviet and East European clinical surveys reporting reversible psychophysiological dysfunctions from chronic low-level exposure.

Migrating birds respond to Project Seafarer's electromagnetic field

Unknown authors · 1977

Researchers used radar to track individual migrating birds flying over a large alternating-current antenna system. The birds turned or changed altitude more frequently when the antenna system was operating than when it was not.

Microwave Auditory Effect—A Comparison of Some Possible Transduction Mechanisms

James C. Lin · 1976

The study compares radiation pressure, restrictive force, and rapid thermal expansion as possible transduction mechanisms for the microwave auditory effect. At a peak absorbed power density of 2400 watt/m² for 2450 MHz radiation, the computed maximum stress is approximately 0.02 Newtons/m², which is above the bone-conduction hearing threshold.

HEALTH HAZARDS FROM TELEMETRY RF EXPOSURE ? A REVIEW ON THE INTERACTIONS BETWEEN ELECTROMAGNETIC FIELDS AND BIOSYSTEMS

Peter A. Neukomm · 1976

Most telemetry equipment operates between 10 and 1000 MHz with radiated power from a few microwatts to approximately 2 W. Hot spots in animal brains show heating potential 10 to 15 times higher than predicted by the RAC method.

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 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.

Sleep & Circadian Rhythm

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.
