Weak ultrashort-wave radiation caused no detectable changes in rats, while strong radiation depressed behavior, stunted growth, roughened fur, and prevented reproduction.

Plain English Summary

Summary written for general audiences

Rats exposed to weak radiation were indistinguishable from non-radiated controls in size, behavior, and reproduction. Rats exposed to strong radiation showed depressed behavior, reduced growth, rough fur, and complete failure to reproduce over months of observation. Histology of heavily irradiated tumors revealed loss of tissue fluid, diffuse necrosis, expanded blood vessels, thrombosis, and very high leukocyte counts. Blood analyses of irradiated rabbits showed abnormal erythrocyte behavior and a strong leukocyte increase peaking at six hours after exposure.

Why This Matters

Control tests with saline at the same temperature produced only temporary vessel dilation that resolved within an hour, while radiation caused a lasting loss of sympathetic tone shown by failure of adrenalin to constrict vessels. Prior work by Schliephake and Haase demonstrated high effectiveness of short waves in destroying various bacteria, which led to therapeutic use in bacterial inflammations.

Finding

It was found, that the weakly-radiated animals were in no way different from the non-radiated ones, in size, in psychic behavior and in reproduction ability

Quick Questions About This Study

Weakly radiated rats showed no differences from non-radiated controls in size, behavior, or reproductive ability.
Strongly radiated rats became lethargic, grew poorly, developed rough fur, and failed to reproduce over the observation period beginning September 1930.
Heavily irradiated tumors showed loss of tissue fluid, diffuse necrosis, expanded and blood-filled vessels, endothelial damage, thrombosis, and very high leukocyte counts.
Radiation caused an initial vessel contraction followed by capillary expansion and a pulsating venous retrocurrent, while warming with saline at the same temperature produced only temporary dilation that resolved within an hour and did not cause a retrocurrent.
