摘要

在绿藻心水藻的营养细胞中，在饱和空气、N2或四种不同的低含氧量气体混合物中的一种的水中，测量了14 MeV中子辐照对杀伤的敏感性。结果表明，辐射灵敏度与氧张力之间的关系符合Howard-Flanders-Alper公式。估计参数为:K = 9·308±0·98±M 1-1, M = 1·724±0·024

Dependence of radiation sensitivity on oxygen tension in Oedogonium—III. Applicability of the Howard-Flanders-Alper formula for 14 MeV neutron irradiation

In vegetative cells of the green alga Oedogonium cardiacum, sensitivity to killing by 14 MeV neutron irradiation has been measured in water saturated with air, N₂, or one of four different low oxygen-content gas mixtures. The results showed a reasonable fit to the Howard-Flanders-Alper formula for the relationship between radiation sensitivity and oxygen tension. The estimated parameters were: K = 9·308 ± 0·98 ͜M 1^-1 and m = 1·724± 0·024
