Effects of Exposure to Microwaves: Problems and Perspectives

Sol M. Michaelson · 1974

Most experimental data supported the concept that the effects of microwave exposure are primarily, if not only, a response to hyperthermia or altered thermal gradients in the body. Extensive investigations showed that for frequencies between 200 and 24,500 MHz, exposure to power density greater than 100 mW/cm? for 1 hr or more could have pathophysiologic manifestations of a thermal nature. At power densities less than 100 mW/cm?, evidence of pathologic change was described as nonexistent or equivocal.

KINETICS OF THE PHOTO-INDUCED EPR SIGNAL IN WHOLE-CELL RHODOSPIRILLUM RUBRUM: EFFECTS OF LIGHT INTENSITY, DARK ADAPTATION, TEMPERATURE, AND MICROWAVE POWER

G. A. CORKER, S. A. SHARPE · 1974

Researchers studied the kinetics of the photo-induced P870* EPR signal in whole-cell Rhodospirillum rubrum at room temperature. At low actinic light intensity the signal growth appeared monotonic with a very slow second phase and the decay was biphasic. Increasing the light intensity caused a rapid initial rise to a plateau within 100 ms followed by slow growth and a monophasic decay.

Changes in certain protective reactions of an organism under the influence of SW in experimental and industrial conditions

Volkova AP, Fukalova PP · 1974

In laboratory experiments, one group of outbred white rats was exposed to 14.88 MHz short waves at 2,250 V/m for one hour, a second group at 100 V/m for four hours, and a third group served as controls. Workers at a station where field intensities exceeded permissible limits showed two-fold lower phagocytic activity and four-fold higher mouth autoflora, while workers at stations within limits had values within normal ranges.

Use of a Bacteriophage System for Investigating the Biological Effects of Low Intensity Pulsed Microwave Radiation

C. M. B. Walker, K. G. McWhirter, W. A. G. Voss · 1974

Researchers examined the effect of 2450 MHz microwave radiation pulsed at 8KHz at a power density between 1 and 10 mW cm* on bacteriophage infection of E. coli, irradiating samples for 7 minutes. They compared the number of infective centers in irradiated samples with controls across 25 experiments. A Student's t-test on the combined data gave t=0.3815 with 48 degrees of freedom, showing about a 50% probability the difference was due to chance.

Comparative Effectiveness of 39- and 2450-MHz Electric Fields for Control of Rice Weevils in Wheat

S. O. Nelson, L. E. Stetson · 1974

Researchers compared 39-MHz and 2450-MHz radiofrequency electric fields for killing adult rice weevils in hard red winter wheat. Complete mortality was reached at 39 MHz with grain temperatures of about 40°C, whereas 2450 MHz needed about 80°C. Insects surviving 39-MHz exposure showed severe injury and high delayed mortality, while those surviving 2450-MHz exposure moved normally. Progeny emergence was nearly eliminated at 39 MHz above 50°C but persisted across most 2450-MHz treatments.
