Biological Effects and Health Implications of Microwave Radiation

Stephen F. Cleary · 1969

The symposium was convened to provide an indication of the present state of the art in biological effects of microwave radiation. There is a great deal of uncertainty concerning the effects of low-intensity microwave and radio-frequency radiation on the mammalian central nervous system. The lack of measurement standards makes intercomparison of data from different investigators difficult or impossible. Federal responsibility for radiation control was established under the Radiation Control for Health and Safety Act of 1968.

Microwave Protection of Plants from Cold

R. G. Bosisio, N. Barthakur · 1969

Researchers measured a reflection coefficient of one per cent and a transmission coefficient of 85% for wax bean leaves at 915 MHz. In a cold chamber at —5°C, microwave radiation of intensity 15 mW/cm² at 2450 MHz raised the leaf temperature to 25°C. The protected plant maintained a leaf temperature of 25°C while the unprotected plant cooled to the ambient temperature of —5°C. After 4 hours the protected plant was still fresh and growing normally, whereas the unprotected plant was completely destroyed.

Effect of Microwaves on the Eye

Leo Birenbaum et al. · 1969

Researchers investigated the acute effects of continuous-wave and pulsed 5.5 GHz microwave radiation on rabbit eyes. They used a closed-waveguide system that delivered power directly to the eye, allowing precise measurement of power entering the eye. Lens opacities appeared within four days after sufficient exposure; three minutes at one watt exceeded the cataractogenic threshold, while two hours at 1/2-watt caused no acute effect. Threshold curves for continuous-wave and pulsed (0.001 duty cycle) radiation showed no substantial difference, indicating that average power determined injury.
