This study deals with using gamma irradiation at low dose average, for determining of the dose response curve of gram-positive and gram-negative bacteria isolates were obtained from Bacteriology Laboratory of Biology Department, College of Science, University of Kufa. The results showed that, the variations of effect in all pathogenic bacteria were studied at range of dose from 0.11 Gy to 0.44 Gy, also the results proved the gram positive bacteria was more resistant to gamma radiation than gram negative bacteria, the inhibition zones for Pseudomonas aeruginosa , Proteusmirabilis , E. coli , Staphylococcus aureus which caused by gamma irradiation reached to ( 0.2 , 0.12 , 0.1 and 0.08mm) respectively compared with that control which was 0.3mm . Application of gamma radiation in treatment pathogenic bacteria revealed that 0.44 (Gy) reduced the viable count of gram negative and positive gram bacteria to become safe.
