[Influence of ionizing radiation of low intensity on the processes of reproduction, aging and dying off of Escherichia coli bacteria].
The influence of 60Co gamma-ray irradiation of low intensity (0.1-0.4, 0.76 x 10(3) microGy/h) on the processes of reproduction, aging and dying off of E. coli B/r and E. coli BS-1 bacteria have been investigated. It was shown that the reproduction of this bacteria strains was not dependent on the dose rate in the range 0.1-0.4 microGy/h. It was shown in comparison with the irradiated E. coli B/r cells dynamics of the aging and dying off of the irradiated E. coli BS-1 is decreased in the process of prolonged (about 190 days) irradiation with a dose rate of 0.76 x 10(3) microGy/h. It is proposed the relationship between the revealed phenomenon of the decrease in the intensity of the irradiated E. coli BS-1 cell aging and dying and the Vavilov-Cerenkov emission.
