OPERANT BEHAVIOR OF RHESUS MONKEYS IN THE PRESENCE OF EXTREMELY LOW FREQUENCY-LOW INTENSITY MAGNETIC AND ELECTRIC FIELDS: EXPERIMENT 2

John de Lorge · 1973

Two male rhesus monkeys were trained to perform fixed-interval, reaction-time, and match-to-sample tasks for food and water reinforcement. In the first phase they were exposed to a 45-Hz, 10-gauss magnetic field with an accompanying electric field for 13 sessions. In the second phase they were exposed to a 10-Hz, 10-gauss magnetic field with a 10-Hz electric field for 12 sessions. No significant behavioral changes were found during 45-Hz exposure, while 10-Hz exposure produced statistically significant but not clinically significant or reproducible effects, and the study concluded that low-intensity ELF fields did not unequivocally cause behavioral changes in nonhuman primates.

GAMMA-AMINOBUTYRIC ACID METABOLISM IN RATS FOLLOWING MICROWAVE EXPOSURE

G. H. Zeman, R. L. Chaput, Z. R. Glaser, L. C. Gershman · 1973

No significant differences in whole brain GABA levels or GAD activity were found between exposed and control rats after any exposure regimen. The authors concluded that altered GABA metabolism is unlikely to be involved in nervous system responses to microwave exposure.

THERMAL REGULATION IN LONG-EVANS RATS EXPOSED TO 2450 MHZ MICROWAVE RADIATION

W.M. Houk, S.M. Michaelson, A. Longacre Jr. · 1973

Researchers measured colonic temperature in 400 unrestrained young male Long-Evans rats exposed to 2450 MHz continuous-wave microwave radiation under constant environmental conditions. The study tested power levels of 9, 18, and 36 mW/cm². At 9 mW/cm² the temperature rise was distinct, maintained throughout the 150-minute exposure, and returned to pre-exposure levels within 30 minutes after exposure, and the rats did not awaken. At 18 mW/cm² the rise was about twice that at 9 mW/cm², similarly sustained, and returned to normal within 30 minutes, with most rats awakening by one hour but resuming rest.

Possible Mechanisms for the Biomolecular Absorption of Microwave Radiation with Functional Implications

James R. Rabinovitz · 1973

The author performed a theoretical analysis of several possible modes of molecular absorption of microwave radiation. Absorption increases rotational energy, allowing segments to occupy different potential wells or tunnel between wells, changing the relative position of segments without altering covalent bonds. These non-covalent structural changes provide a model for direct interference with biomolecular functions that depend on internal three-dimensional structure.

EFFECT OF 2450 MHz MICROWAVE FIELDS ON PERIPHERAL NERVES

C.K. CHOU, ARTHUR W. GUY · 1973

The study used a waveguide filled with temperature-controlled Ringer's solution to expose nerves to CW and pulsed 2450 MHz fields. Frog and cat nerves were tested. Each exposure run lasted 20 minutes with the circulator on for the first 10 minutes and off for the final 10 minutes. Absorbed power densities ranged from 0.003 to 1.7 W/cc for CW and 0.3 to 30 W/cc peak for pulsed fields. No changes in compound action potential amplitude, conduction velocity, or excitability were observed while the circulator was on at any power level.

UHF IRRADIATION AND THE WORKER IN INDUSTRY

M. N. Sadchikov et al. · 1972

Researchers examined 59 workers with radiowave disease who were exposed to UHF electromagnetic fields up to several milliwatts per 1 em. Extracranial vessels showed a similar 48 percent reduction in hyperemia and a 57 percent increase in tone, while peripheral circulation in hands and feet remained within normal ranges. Rabbits irradiated at 50 microvolts per em2 for four hours daily over four months showed reduced phagocytic activity.

Impact of Extremely Low Frequency Electromagnetic Fields on Soil Arthropods

Bernard Greenberg · 1972

Researchers periodically surveyed springtails and three groups of mites during summer 1971 at four habitats along the Sanguine antenna and a power substation plot, with control sites 7 to 12 miles away. Fourteen of 16 tests showed no significant differences in arthropod abundance between test and control sites. The two marginal differences each involved only one arthropod group, with one showing more springtails in the control plot and the other showing more cryptostigmatid mites in the test plot, though both differences were of doubtful significance. Midsummer population peaks occurred in both test and control plots, and community ratios remained stable over two years of antenna operation, indicating no Sanguine effect.
