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.

Field surveys of 494 microwave oven units found that 109 units, or 22 percent, emitted radiation greater than 10 mW/cm² under normal operating conditions. Laboratory measurements demonstrated that power densities exceeding 700 mW/cm² could be produced if door safety interlocks failed or were defeated and the door was wide open. No specific performance standard for microwave oven exposure had been promulgated at the time of the report. Known human bioeffects from microwave exposure at levels of several mW/cm² to several hundred mW/cm² included temporary sterility in males, eye cataracts, and blood changes. A single case report described a microwave oven repairman with a recurrent hemorrhagic eruption that was suggested as possibly caused by microwave energy from microwave ovens.

Researchers tested CNS function in albino rats during chronic 5-month irradiation with millimeter waves at 10 mW/cm² for 60 minutes daily. The earliest change was a lengthening of the latent period accompanied by a decrease in motor response strength.

Researchers prepared cells and their fractions and measured microwave absorption at various frequencies. DNA showed higher microwave absorption than RNA. The study found that microwave absorption by cells affects biological processes.

Researchers developed a microscopic technique to directly observe resin distribution in paper by dissolving cellulose with hydrofluoric acid. Microwave drying for 30-40 seconds produced more resin in the middle of the cross-section compared to conventional drying or shorter microwave exposure.
