title: Studies on possible genetic effects of microwaves in procaryotic and eucaryotic cells.
abstract: The biological effects of microwaves in the hyperfrequency range, 9,4 GHz, and 70-75 GHz were investigated in bacteria and yeast. At power densities below 60 mW/cm2 and SAR values not exceeding 28 mW/g no significant effects on survival of repair competent an deficient strains were observed in Escherichia coli and Saccharomyces cerevisiae. In addition, microwaves of 17 GHz did not induce mutations in E. coli B/r WP2 trp- uvr- above the spontaneous level, and the induction of nuclear reversions, cytoplasmic "petite" mutations and mitotic recombination as well as the efficiency of sporulation was not affected in yeast.
