title: Frequency of sister chromatid exchanges in cigarette smokers.
abstract: The effect of cigarette smoking on the frequency of sister chromatid exchanges (SCE'S) was investigated in a group of adult men. It was observed that there was a significant increase in the mean SCE frequency per cell in smokers. Both the duration of smoking and the number of cigarettes smoked per day appeared to influence SCE frequency.
