Abstract
This research program was initiated with the overall objective of determining genetic and cellular effects from exposure of unicellular organisms to selected frequencies of CW and pulsed microwave radiation which is prevalent in the biosphere. Several tester strains of the bacterium Salmonella typimurium, TA-98, TA-100, TA-1535 and TA-1538; the bacterium Escherichia coli, W3110 (pol A) and p3438 (pol A-, repair deficient); and the yeast Saccharomyces cerevisiae, D3, D4 and D5 were tested for lethal and mutagenic events. Effects of known elevated temperatures were studied to distinguish microwave induced temperature effects from the direct temperature effects. Three kinds of microwave exposure systems were used in these studies: (1) farfield antenna (for 2.45 GHz and 8.5 - 9.5 GHz), (2) waveguide (for 8-10 GHz) and (3) TEM (transverse electric and magnetic mode) transmission lines for 915 MHz radiation. The SAR (specific absorption rate) for various exposures ranged from 0.1 W/kg to 40 W/kg. Pulse repetition rates were 400 Hz and 1000 Hz for pulsed microwave radiations. The studies revealed no increase in mutations or of gene conversions when cells were exposed to microwave radiations, but yeast and bacterial strains showed cellular lethality caused by temperature rises (greater than 10C) at higher power levels.
