Abstract

The effects of gamma radiation from (60)Co and (137)Cs on DNA in aqueous solution are studied experimentally. Using an improved plasmid purification protocol and improved electrophoretic gel analysis techniques provided results with relatively small uncertainties. The results are compared with both theoretical and experimental results. In particular, the results obtained here are discussed in the light of recent discussion on supposed differences of the effects induced by gamma radiation from (60)Co and (137)Cs. We find that the effects of both types of gamma radiation are similar.

摘要

对来自钴60（⁶⁰Co）和铯137（¹³⁷Cs）的伽马辐射对水溶液中DNA的影响进行了实验研究。使用改进的质粒纯化方案和改进的电泳凝胶分析技术得到了不确定性相对较小的结果。将这些结果与理论和实验结果进行了比较。特别是，根据最近关于⁶⁰Co和¹³⁷Cs的伽马辐射所诱导效应的假定差异的讨论，对这里获得的结果进行了探讨。我们发现这两种伽马辐射的效应是相似的。
