[The influence of ionizing radiation of high intensity on the viability of Escherichia coli bacteria, cultivated in the salt buffer without nutrient additions].

The influence of 60Co gamma-ray radiation of high intensity (85 Gy/min) on the viability of E. coli B/r and E. coli BS-1 bacteria, cultivated in salt buffer with the concentration about 10(8) cells/ml, was studied. It was determined that under the doses, which induce about 80% of death of the cells, the irradiated bacteria, just like the intact cells, die during the incubation processes, while under the doses induced the death of cells above 95%, the cells viability of the both strains increases and reaches the constant value by the byhend 2nd-5th days of incubation in these conditions. In the result of the differences of the reactions of the intact and irradiated with different doses of radiation microorganisms on the incubation during their postradiational period in the phosphate buffer we have the fact of the absence of the dependence of the effect from the dose, or the decreasing of the consequences of the radiation under the increasing of the dose of the radiation. The nature of this phenomenology while stays not understood.
