Abstract
It was shown that under the effect of sparsely ionizing radiation double-strand DNA breaks in solution were formed more readily at high dose-rates (20 Gy/min) than at low ones (0.03-0.06 Gy/min). Possible mechanisms of the effect observed are discussed.
摘要
结果表明，在低剂量电离辐射的作用下，溶液中的双链DNA断裂在高剂量率（20 Gy/分钟）时比在低剂量率（0.03 - 0.06 Gy/分钟）时更容易形成。文中讨论了观察到该效应的可能机制。
