[Effect of ionizing irradiation of low intensity on the viability of Escherichia coli bacteria, cultivated in the salt buffer].
The influence of 60Co gamma-ray irradiation of low intensity (0.35 Gy/min) on the viability of Escherichia coli B/r and Escherichia coli BS-1 bacteria cultivated in salt buffer in concentration of 10(8) cell/ml was investigated. It was shown that under the doses induced the cell killing about 60-75%, the irradiated bacteria, like intact cell, were killed during the incubation process, while after the doses induced the cell killing above 99% of cell population, the bacteria viability of the both strains was increased. The increase reaches a certain value on the 2-5 the days of bacterial incubation in this conditions. The nature of observed phenomenology is vague for the present.
