IMPI Course on Industrial, Scientific and Medical Uses of Microwaves

Unknown authors · 1979

The one-day course was held on March 28, 1979 at the Philip Morris Research Center in Richmond, Virginia. The course aimed to present microwave theory and its applications in industry, analysis, and medicine, and to give special consideration to microwave health effects and safety.

INDUSTRIAL HYGIENE WALK-THROUGH SURVEY REPORT ON RF RADIATION EXPOSURES FROM HEAT SEALERS

Clinton Cox, Betsy Egan, Bill Murray, Bob Herrick · 1979

On November 29, 1978, NIOSH conducted a walk-through survey of the RF sealing area at Standard Plastic Products in South Plainfield, New Jersey. The purpose was to identify workers for a study on health effects from occupational radio frequency radiation exposure. Electric and magnetic fields from the heat sealers were measured and corrected for duty cycle. All three sealers produced electric fields greater than 1000 V/M, exceeding the ANSI guideline of 200 V/M by at least five times. A cohort of 15 workers, mostly elderly women, was identified and could be used in a study if combined with similar cohorts from other plants.

Inexpensive Microwave Survey Instruments: An Evaluation

William A. Herman, Donald M. Witters, Jr. · 1979

Researchers tested three inexpensive microwave survey instruments—the Micromate, Guard-Rod, and Interceptor/Microscan—and evaluated several test parameters. Cross-polarized fields increased the Micromate’s sensitivity by 216 % and the Guard-Rod’s by up to 694 %; amplitude-modulated fields increased the Micromate’s sensitivity by 119 % and decreased the Guard-Rod’s by up to 64.5 %; the Interceptor/Microscan responded to peak power, increasing sensitivity fivefold.

Search for Millimeter Microwave Effects on Enzyme or Protein Functions

P. Tuengler, F. Keilmann, L. Genzel · 1979

The study tested whether millimeter microwaves affect the function of alcohol dehydrogenase and hemoglobin in vitro. Alcohol dehydrogenase was exposed to 40–115 GHz radiation at near 10 mW/cm² while monitoring the reaction rate via NADH absorption using a 337 nm filter. No change in alcohol dehydrogenase turnover rate was detected within a sensitivity of 0.1%. Hemoglobin at half-oxygenation was exposed to absorbed intensity of 3–13 mW/cm² across 40–115 GHz. No shift in the equilibrium oxygen constant of half-oxygenated hemoglobin was detected within a sensitivity of 0.4%.

MEASUREMENT OF POTENTIALLY HAZARDOUS ELECTROMAGNETIC FIELDS--RF AND MICROWAVE

Unknown authors · 1978

Instruments should read average power density, mean squared electric field strength, mean squared magnetic field strength, or energy density. Calibration methods include free-space standard field, guided wave methods, and standard probe method.

The biological effects of magnetic fields on man

E.E. KETCHEN, W.E. PORTER, N.E. BOLTON · 1978

Human exposures up to 20,000 G produced only transient sensations such as a metallic taste or tooth pain in individuals with dental fillings, while Soviet magnet-fabrication workers reported cardiovascular and neurological symptoms at unspecified field strengths. In rabbits, stationary fields of 200–1000 G for 1–3 minutes altered EEG patterns, with a threshold around 100 G, and long-term exposure caused neuroglial and neuronal lesions. Mice exposed to 4200–9000 G showed a significant decrease in bone-marrow megakaryocytes and a statistically significant increase in splenic megakaryocytes.

Influence of a Constant Magnetic Field on Nervous Tissues: I. Nerve Conduction Velocity Studies

Jean-Louis Schwartz · 1978

Researchers studied the circumesophageal connective of the lobster to investigate the influence of a constant magnetic field on nerve impulse conduction velocity. They found no significant effect of a 1.2 T magnetic field on conduction velocity in either parallel or perpendicular configurations.

Tests for Human Perception of 60 Hz Moderate Strength Magnetic Fields

Robert D. Tucker, Otto H. Schmitt · 1978

Each trial asked the subject to decide whether a 60 Hz magnetic field of 7.5–15 gauss was present, with the field randomized by computer. After more than 30,000 total trials, no individual performed better than chance, and group results were consistent with no real perception.
