AN OPERANT ELECTROMAGNETIC CHAMBER

Willard E. Caldwell, Earl Gaddis, Morton Werber · 1969

Researchers built an Operant Electromagnetic Chamber with a shielded section and an unshielded section, and exposed animals to 8840 mc radio frequency at a power density of 2.2 to 2.5 milliwatts per square inch. No significant difference in shielded-chamber time occurred when the radio frequency was on during the first half of trials, but when it was on during the second half the animals stayed in the shielded area significantly longer with the frequency off (p < .01).

BIOLOGICAL ACTIVITY AND SOLAR ELECTROMAGNETIC RADIATION

Unknown authors · 1969

Researchers observed that the yield of two-week rice seedlings fluctuated significantly over 20 days and correlated negatively with solar chromospheric activity indices. In a controlled experiment, water uptake of germinating bean seeds showed a strong negative correlation with geomagnetic activity indices over nine days. Both experiments found that biological variability increased with higher solar activity indices. The authors concluded that solar activity slows growth and germination while increasing their variability.

R-f pollution: a rising concern

Unknown authors · 1969

Researchers placed laboratory rats in an irradiation tank circuit to test their tolerance to radiation at 6, 14, and 21 MHz. The tests showed harmful effects to the gastrointestinal, cardiovascular, respiratory, and genito-urinary systems, peaking at 35 days after irradiation. No changes were detected in the endocrine system of the test animals.

Non-ionizing radiation - the physical relationship between typical sources and human targets

A. G. Hunt · 1969

The author interprets typical radiation sources as applied to human targets and identifies deficiencies in applying available information to determine safe working levels. Laser radiation problems are discussed with particular attention drawn to the critical near infra-red region. The paper suggests improved data is required for spectral biological effects at all wavelengths with emphasis on damage threshold levels.
