Effect of prior X-irradiation on ultraviolet light-induced sister-chromatid exchange
Mutation Research
|March 1, 1984
Abstract:
Induction of sister-chromatid exchanges (SCEs) by ultraviolet light at 2.6 J/m2 in Chinese hamster ovary cells was significantly inhibited by pretreatment with 3 and 5 Gy of X-rays. No inhibition was observed when cells were treated first with ultraviolet light and subsequently X-irradiated with 5 Gy.
