Abstract

Ionizing radiation generates isolated and localized multiple (i.e., clustered) lesions in DNA, and the latter is believed to be primarily responsible for deleterious biological consequences such as cell killing and mutations. In the present study, we irradiated plasmid and lambda DNA by ionizing radiations with different linear energy transfer (LET) values, and compared the yields of isolated and clustered DNA lesions.
