Survival of Escherichia coli strains differing in DNA repair capability after irradiation by fission-spectrum neutrons
Journal Article

· Radiat. Res.; (United States)
The survival of Escherichia coli strains K12 AB1157, AB2463, AB1886, and AB2480 was measured after irradiation with fission neutrons from the Argonne JANUS facility. All inactivations were exponential. Strains AB1157, AB2463, and AB1886 had similar sensitivities, whereas AB2480 was about twice as sensitive (D/sub 0/ values of 4 x 10/sup 3/ and 1.7 x 10/sup 3/ rad, respectively). No increases in mutation caused by neutrons were observed in strain AB1157 (at 5% survival level) or in strain AB2480 (at 0.2% survival level) for induction of resistance to phage T5.
