[Does a powerful electromagnetic field in the decimetric range possess genetic activity in relation to...

It was shown that mutants can occur in various microorganisms after a short-term exposure to electromagnetic field of 40 to 100 W/cm3 at 2375 MHz. Induction of mutants usually increases as the temperature rises and cell death rate grows to reach a maximum at a minimum survival rate. Colonial-morphological and biochemical phenotype changes are noted. Both specific and individual radiosensitivity are observed (from a 100 per cent loss of the studied character to the complete absence of the effect). Changes occur more frequently in the parameters determined by plasmids. There is a possibility to select thermoresistant variants without changing the genotype.
