From effects of neutron irradiation upon cell function; Neuherberg, F.R. Germany (22 Oct 1973). Procedures are described for irradiating Tradescantia cuttings with neutrons and x rays. Stamen hairs were scored for various mutations. Results are discussed under the following headings: experimental end points and RBE; influence of dose on RBE; effect of dose rate on RBE; influence of neutron energy on RBE; the RBE of 3.9 GeV nitrogen ions; the influence of hypoxia (OER); and the influence of chromosome volume and ploidy level on RBE; pollen abortion data. Graphs are presented to show survival curves for stamen hairs after neutron and x irradiation and neutron and x-ray dose-response curves for pink mutants, blue giant cells. and colorless mutants.
