Abstract
A study was made of the sensitivity of E. coli (the wild type, rec A13 and Gamr 444 mutants) to gamma- and alpha-radiation. The most pronounced differences in radiosensitivity of the strains under study were noted with gamma-radiation. The sensitivity of the studied strains to alpha-radiation was levelled. The authors discuss the mechanisms of the effects observed in various E. coli strains exposed to ionizing radiation of different LET.
摘要
对大肠杆菌（野生型、rec A13和Gamr 444突变体）对γ射线和α射线的敏感性进行了研究。在所研究的菌株中，γ射线照射下的放射敏感性差异最为明显。所研究菌株对α射线的敏感性趋于一致。作者讨论了不同线性能量传递（LET）的电离辐射作用于各种大肠杆菌菌株时所观察到的效应机制。
