Abstract
Strain  of the yeast Saccharomyces cerevisiae, and
strains TA-1535, TA-100 and TA-98 of the bacterium Salmonella typhimurium, were exposed to 2.45-GHz continuous
wave or 8.5 to 9.6-GHz pulsed electromagnetic radiation (EMR) at various
power densities from 1 to 45 mW/cm². The temperature during radiation was
maintained at 30°C
for yeast cultures and at 37°C
for bacterial cultures. The studies revealed no increase in mutations or of
mitotic gene conversions when cells were radiated for two hours or less.
Decreased viability of cells was noted in all cultures tested after radiation
at power densities of 30 mW/cm² or more; however, no
reliable changes in genetic events occurred.
