The radiation chemistry of DNA constituents has been a subject for intensive studies, because the DNA is considered to be one of the most vital targets of ionizing radiation that leads to lethal damage of bacterial and mammalian cells.', 2 It is suggested by a number of workers that radiolyses of pyrimidine bases and related nucleosides in aqueous solution under deaerated conditions give the possible dimeric products3-'as well as those from the ...
