WebJun 1, 2024 · Abstract. In the radiation sterilization arena, the question often arises as to whether radiation resistance of microorganisms might be affected by the energy level of the radiation source and the rate of the dose delivered (kGy/time). The basis for the question is if the microbial lethality is affected by the radiation energy level and/or the ... WebJan 1, 2014 · Irradiation to 25 kGy resulted in 6 logs reduction in the concentration of live bacteria; however, growth could be detected in the stock and the first 10-fold dilution. No growth was detected in the sample that received 50 kGy of gamma irradiation, demonstrating that at least 8 logs of inactivation were achieved. crypton 2014 ed WebApr 30, 2024 · Energy of the ionizing radiation (electron beam or gamma rays) passes through the material, disrupting the pathogens that cause contamination. A minimum dose of 25 kGy was routinely applied for the sterilization of many medical devices, pharmaceutical products and biological tissues . WebA minimum absorbed dose of 25 kGy may be regarded as adequate for the purpose of sterilising pharmaceutical components or products which have a low initial bioburden and no radioresistant spores. Other doses may be used provided that a biological validation has been performed. 4.
