MEASUREMENTS OF ELECTROMAGNETIC ACTIVITIES OF THE HUMAN BODY IN THE FREQUENCY REGION 1 kHz - 2 GHz

Unknown authors

Researchers investigated electromagnetic emissions from the human body across the frequency region 10^3 Hz - 2-10^9 Hz using tunable radiometers. They found that the body acts as a purely thermal radiator down to about 10^4 Hz, with radiation temperature equal to body temperature at all tested positions above that frequency. Below 10^4 Hz, emissions exceeded thermal levels and varied with electrode type, location, and muscle state, peaking with coaxial needle electrodes in contracted muscle.

RADIO FREQUENCY HAZARDS

John Roman

Animal experiments have largely been performed using small fur-bearing animals such as mice, rabbits and dogs, but results are difficult to extrapolate to humans. The eye and the testis are the two body organs most seriously affected by heat. Due to overheating, the eye may develop opacities or cataracts, and these are irreversible, while damage to the testis induces temporary sterility.

RADIOFREQUENCY RADIATION EXPOSURE STANDARDS

Unknown authors

This technical report examines radiofrequency radiation exposure standards, focusing on power density measurements and regulatory frameworks. The document appears to analyze current exposure limits and assessment methods for RF radiation from wireless technologies. This type of standards review is crucial for understanding whether current safety guidelines adequately protect public health.

Microwaves induce an increase in the frequency of complement receptor-bearing lymphoid spleen cells in mice

Unknown authors

This mouse study investigated how microwave radiation exposure affects immune system cells in the spleen, specifically looking at lymphoid cells that carry complement receptors. The researchers found that microwave exposure increased the frequency of these immune cells, suggesting that microwave radiation can alter immune system function at the cellular level.

HYPERBARIA AND RADIATION

S. M. Michaelson

This conference paper by researcher S.M. Michaelson examined how microwave radiation affects rodents under hyperbaric (high pressure) conditions. The study investigated whether increased atmospheric pressure changes how animals respond to microwave exposure, particularly regarding thermal regulation and other physiological processes.

CHARACTERISTICS AND MEASUREMENTS OF MICROWAVE AND RADIOFREQUENCY RADIATION

Bureau of Radiological Health, Food and Drug Administration

Microwaves and RF fields are almost totally reflected from metals, transmitted through plastics, ceramics, paper, or glass, and absorbed by most biological materials, particularly those with high water content. The document explains near-field and far-field regions, noting that the near field dominates when the distance is much smaller than the wavelength and that the far field begins where the ratio of electric to magnetic field approaches 377 ohms. It specifies measurement techniques for frequencies from 1 MHz to 100 GHz and distinguishes emission standards from exposure standards.

ELIMINATION OF MICROWAVE EFFECTS ON THE VITALITY OF NERVES AFTER ACTIVE TRANSPORT HAS BEEN BLOCKED

Unknown authors

Researchers exposed paired frog sciatic nerves treated with ouabain to microwaves at a specific absorption rate of 10 W/kg while stimulating at 50 pulse pairs per second. At 50 ppps, ouabain reduced the half-decay time from about two hours to under 30 minutes, and microwave exposure caused no significant further shortening. At a lower stimulation rate of 5 ppps, half-decay times returned to near two hours and again showed no significant difference between exposed and unexposed nerves. The authors suggested that microwave effects on nerve vitality are associated with decay of ionic gradients normally maintained by active transport.
