Abstract
IT is well known that the presence of oxygen during the irradiation of biological materials by X- or gamma-rays usually increases the amount of radiation damage. At the cellular level a considerable amount of quantitative data exists on the effect of oxygen, given during irradiation, on the yield of chromosome aberrations1, but little information is available concerning the influence of oxygen on the amount of mitotic inhibition. Early work on the fall in mitotic index values of broad bean root tips2 and the more recent studies on mitotic rates of Chortophaga neuroblasts3 and Tradescantia microspores4 have all indicated that the degree of mitotic inhibition is dependent on the amount of oxygen present during irradiation.
