GROWTH OF HUMAN BONE MARROW CELLS IN AGAR CULTURE UNDER THE INFLUENCE OF ELECTRICAL CURRENTS

Unknown authors · 1977

Researchers cultured human bone marrow cells in agar and exposed them to AC and DC electrical currents for 7 days. Symmetrical AC impulse current had no effect on cell growth. DC current greater than 10 pA caused severe growth reduction and protein electrophoresis. The growth reduction was proportional to the logarithm of the AC current amplitudes. The reduction was not related to induction, pH changes, or protein electrophoresis.

A SYSTEM FOR DETERMINING THE RADIOFREQUENCY ABSORPTION COEFFICIENT OF THE HUMAN BODY IN THE HIGH FREQUENCY BAND

Douglas A. Hill et al. · 1977

Researchers built a rectangular coaxial TEM cell to measure radiofrequency absorption in the human body from 10 to 26 MHz radiation. They made 17 preliminary measurements on three volunteers at 23.25 MHz, finding absorption results reproducible for each subject but differing between subjects. With 400 W incident power producing 1 mW/cm² power density, subjects absorbed 0 to 2 W, with higher absorption in EKH orientation than KEH orientation, and EKH absorption exceeded ellipsoid model predictions.

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.

Phytotoxicity threshold levels of microwave radiation for Trifolium and Medicago seeds

A. E. Crawford · 1977

The study used four cultivars of small seeded legumes. Seeds were irradiated in a domestic microwave oven at 2450 mHz with a power setting of 690 W for 5, 10, 15, 20, 30, and 45 seconds. White clover 'Kersey', 'Kent', and red clover 'Hungaropoly' showed increased germination and reduced hard seeds at 5–15 seconds, while lucerne 'Eynsford' had only a slight germination increase, and all species experienced a sharp germination decline at 20 seconds with near-complete mortality beyond 30 seconds.

RF Cell Culture Irradiation System with Controlled Temperature and Field Strength

Arthur W. Guy · 1977

The system was designed for the National Institute for Occupational Safety and Health to determine human RF exposure thresholds in the frequency range D.C. to 100 MHz. The final design uses concentric stainless steel rings with a teflon bottom that forms a liquid-tight seal compressed by brass retainer clamps.

THE PHYSICAL BASIS OF ELECTROMAGNETIC INTERACTIONS WITH BIOLOGICAL SYSTEMS

Leonard S. Taylor, Augustine Y. Cheung · 1977

The paper reviews representative studies on microwave and radiofrequency biological effects and proposed interaction mechanisms. The review considers neuroendocrine alterations, hematopoietic effects, and effects on neural systems. Studies report alterations in CNS bioelectrical activity, behavior, and excitable cell systems at microwave intensities of 10 mi/om² or less.

REVIEW OF OCCUPATIONAL SAFETY AND HEALTH ASPECTS OF ELECTROMAGNETIC PULSE EXPOSURE

A. Bruner · 1977

The report describes the typical occupational exposure to EMP at simulator facilities and summarizes medical surveillance observations. Data from informal observations and comprehensive annual physical examinations of approximately 600 workers exposed to various EMPs over a number of years disclosed no adverse health effects attributable to EMP exposure. A rodent study with continuous exposure to 447,000 V/m at 5 pulses per second for 38 weeks found no injurious effects. Bell Laboratories reported no noticeable effects in over ten persons exposed to pulses up to 100 kV/m. The Navy and other companies also reported no EMP health effects to OSHA in 1974.

AN OPTICAL NON-PERTURBING PROBE FOR TEMPERATURE MEASUREMENTS IN BIOLOGICAL MATERIALS EXPOSED TO MICROWAVE RADIATION

P. E. Schoen, J. M. Schnur, J. P. Sheridan · 1977

Researchers placed a ruby fragment smaller than 50 µm in a thin-walled capillary with a biological sample and equilibrated it in a thermostatted chamber controlled to ±0.15°C. They measured the ruby R1 fluorescence frequency shift relative to an argon reference line across temperatures. The frequency shift showed a linear relationship with temperature with a slope of 0.141 cm-1/°C. The method achieved a temperature measurement precision of 0.21°C. Tests in 2.4 GHz microwave fields showed no perturbation of the fields or the calibration curve.

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.
