Biological Effects of Millimeter-Wave Irradiation: Living Bacterial Organisms.
Abstract
The report describes experiments on the effects of millimeter-wave irradiation on the mutation rates of Salmonella typhimurium straisn TA 1535 and TA 1538. No frequency-sensitive irradiation effects have been observed in spite of closely spaced frequencies used in the 42-48 and 65-75 GHz bands. Some preliminary experiments performed with yeast Saccharomyces cerevisiae have given rates of growth that are dependent on the irradiation frequency. However, on account of the high degree of variability, accurate frequency resettability is a must before firm conclusions can be drawn. A new method for measuring complex permittivities of biological media in vitro and in vivo has been proposed and tested for feasibility. Raman laser spectroscopy is proposed as a means of searching for frequency-specific biological effects of millimeter-wave irradiation. The Raman system setup for these studies is used for pilot studies with vesicular stomatitis, Sindbis, and LaCrosse viruses and with bacillus megaterium.
