WebJul 31, 2024 · The technique was optimized by Crowe and colleagues, and a nickel-copper alloy was used instead of brass to cover the applicator, so that more beta-radiation was emitted that decreased the necessary application time and reduced the gamma-radiation load on tissues other than the nasopharyngeal lymphoid tissue. WebResistance of microorganisms to gamma radiation is mainly dependent on the microorganisms' capability to repair single strand breaks due to the activity of their DNA repair enzymes ( 13 ). Strains which don't have this competence are a lot more radiosensitive than the others ( 14 ).
