Abstract: The goal of this study effect radiation on a number of Staphylococcus aureus bacterial isolates collected from Hilla Teaching Hospital and Imam Ali Hospital in Babil Governorate and Baghdad hospitals different patients randomly from from burns, wounds, urinary tract infections and skin with burn and wounds infections. Identification by VITECK2-GP, S.aureus were implanted on Nutrient broth and Nutrient agar , then placed within test tube containing distilled water 5ml, then exposing to an different radiosources including CS137 and CO60, with activity 1-10 µc with different radiation doses for different peroids 1-2-3 hrs.; implanted on Petridishes plates of Nuterinat agar incubated in the incubator for 24 hrs. at 37 ° C . The results of exposure to beta and gamma rays emitted by CS 137 and CO 60 radiosources with activity 10 µci and 1 µci. for 1hrs.,2hrs. 3hrs, with different doses including Cs (10 µci) Beta 3.160*10-1 (1hrs.), 6.32*10-1 (2hrs.), 9.48*10-1 (3hrs.) 98.3%, 99.5%, 99.5% respectively ; Cs (10 µci) Gamma5.815*10-1 (1hrs.), 11.63*10-1 (2hrs.), 17.445*10-1 (3hrs.) 98.9%, 99.6%, 99.5% respectively; Cs (1 µci) Beta 3.417*10-1 (1hrs.) , 6.835*10-1 (2hrs.), 9.253*10-1 (3hrs.), 99.3%, 99.5%, 99.9% respectively ; Cs (1 µci) Gamma 6.289*10-1 (1hrs.), 12.678*10-1 (2hrs.), 18.867*10-1 (3hrs.) 99.2%, 99.6%, 99.8% respectively; Coblit with Co(1 µci) Beta 1.2*10-1 (1hrs.), 2.4*10-1 (2hrs.), 3.6*10-1 (3hrs.) 99.4%, 99.2%, 99.8%; Co(10 µci) Beta, 1.86*10-1 (1hrs.), 3.7*10-1 (2hrs.), 5.5*10-1 (3hrs.) 99.6%, 99.8%, 99.9% respectively ; Co(10 µci) Gamma, 2.33*10-6 (1hrs.), 4.66*10-6 (2hrs.), 6.99*10-6 (3hrs.), 95.2%, 99.8%, 99.8% respectively. Calculate number of colonies with percentage of killing.
