Research Abstract

We examined the contributions of OH radical mediated indirect action of X-irradiation on cell killing of CHO, AA8, xrs-6 and 51D1 cells under oxic and hypoxic conditions. The contributions of indirect action for xrs-6 cells under both conditions showed lower than that for CHO, AA8 and 51D1 cell lines.
