Radiation-induced delays in cell progression in Vicia faba root meristems. [X radiation, neutrons]
A relative comparison of sequential colchicine accumulations of mitotic cells has been used to assess delays in cell progression after x and 0.32-MeV neutron irradiation. The relative proportions of cells progressing (surviving) into mitosis show a near exponential relation with dose, and allow analysis in an analogous manner to survival studies. Relative biological effectiveness varies with the time period chosen; it increases with decreasing dose when there is a quadratic component in the x-ray data to a maximum of 7.0 in the neutron dose range covered. The relative cell progressions in the period 2 to 8 hr postirradiation appear best suited to comparative analysis between radiations of different quality.
