STUDIES ON THERAPEUTIC HEATING BY ELECTROMAGNETIC ENERGY

Arthur W. Guy et al. · 1972

This paper summarizes some results of both theoretical and experimental analyses on the electromagnetic heating patterns in multilayered human tissues. Planar, cylindrical, and irregular-shaped layers of human tissue exposed to various electromagnetic sources such as dipoles and rectangular apertures are considered. Thermographic studies on electrically equivalent phantom models of human tissue structures have facilitated the acquisition and interpretation of the experimental data. The results show a general improvement with decreasing frequency of the therapeutic heating patterns of applicators operating in the frequency range of 433 MHz to 2450 MHz.

Radiation Exposure from Industrial Microwave Applications

John A. Eure, James W. Nicolls, Robert L. Elder · 1972

In the spring of 1970 the Bureau of Radiological Health conducted an initial investigation and surveyed a sample of industrial microwave applications to determine potential health hazards. Fifteen conveyorized units operating at 915 MHz or 2450 MHz with powers from 2 kW to 120 kW were measured. Leakage at operator eye level did not exceed 4.0 mW/cm², but maximum leakage at cleaning doors and conveyor slots ranged from below 1.0 to over 200 mW/cm². Units less than one year old emitted no more than 8.0 mW/cm² at conveyor slots, and the authors concluded that with proper maintenance leakage can approach 10 mW/cm² or less at any accessible surface.

CHANGE IN METABOLISM OF NITROGENOUS SUBSTANCES IN ANIMAL NERVE TISSUE UNDER EFFECT OF ELECTROMAGNETIC FIELD OF SUPERHIGH FREQUENCY

L. I. Mishchenko, S. P. Frenkel · 1972

Researchers studied ammonia, glutamine, glutamate, amide nitrogen of proteins, AMP, and AMP desaminase activity in the brain of rats exposed to electric and magnetic fields of superhigh frequency. Electric field exposure increased ammonia, amide nitrogen in proteins, and AMP desaminase activity, which the authors suggest may be largely due to a decrease in ammonia and glutamine. Magnetic field exposure decreased ammonia and glutamine while increasing AMP and amide nitrogen in brain proteins.

Federal/State Radiation Control Legislation 1972

Lois A. Miller · 1972

The report reviews Federal and State radiation control legislation for calendar year 1972, organized by Federal/State, subject, and status. Thirty-seven State legislatures met in regular session and five in special session during 1972. Nineteen Federal bills and 167 State bills were introduced, and 30 bills were enacted including three Federal bills.

Human Exposure to Nonionizing Radiant Energy—Potential Hazards and Safety Standards

S. M. Michaelson · 1972

The paper reviews the pathophysiology of exposure to ultraviolet, infrared, coherent electromagnetic radiation (laser), microwaves, and radio-frequency radiation and the protection guides established for these energies. It states that setting protection standards is a very complicated process because of numerous variables and difficulty obtaining valid data. The objectives of protection are to prevent acute effects and to limit the risks of late effects. Protection standards are the results of empirical approaches to various problems reflecting current qualitative and quantitative knowledge.

A Time-Domain Technique for Measurement of the Dielectric Properties of Biological Substances

Magdy F. Iskander, Stanislaw S. Stuchly · 1972

Researchers described a time-domain reflectometry method for broadband measurement of dielectric properties using a small shunt capacitor as a sample holder. The method requires sample volumes of only a few cubic millimeters. The technique offers speed, simplicity, and ease of data evaluation.

THE NATURE OF ELECTROSENSING IN THE FISH

ALLAN H. FREY, EDWIN S. EICHERT III · 1972

The biological database was weak but useful for developing a mathematical model and analyzing sense mechanisms. They suggested a working hypothesis for the electrosensor mechanism that may collapse current receptor categorizations. They indicated the linkage among neural coding schemes and showed their essential identity. A mathematical model was developed from usable experimental data and analyzed by computer to ascertain receptor sensitivity requirements and effects of variables like fish size and object distance.

PECULIARITIES OF NITROGEN METABOLISM IN THE RAT BRAIN UNDER EFFECT OF IMPULSIVE ELECTROMAGNETIC FIELD OF LOW FREQUENCY

F. A. Kolodub, H. I. Evtushenko · 1972

Researchers studied nitrogen metabolism in rat brain during exposure to a 7 kHz impulsive electromagnetic field at 24 and 72 kA/m. At 72 kA/m, ammonia and glutaminic acid content decreased while amide nitrogen of proteins was unchanged and adenylic acid desamination and glutamine synthesis were inhibited due to ATP deficit. At 24 kA/m with chronic exposure, ammonia shifts were phase-like and occurred without a corresponding rise in glutamine.
