Effect of small doses of X-rays on formation of colour variants bySerratia marcescens

Abstract

(1) Cells ofSerratia marcescens which survive repeated irradiation with X-rays are capable, after a further single dose of irradiation, of forming a higher percentage of variants. The percentage of variants increases almost linearly in relation to the dose. (2) A deviation from this linear course occurs in the small dose range (34 r. to 160 r.). The… (More)
