Effects of 60Co gamma-rays and 252Cf neutrons on human sperm chromosomes were studied using our interspecific in vitro fertilization system to estimate relative biological effectiveness (RBE) of neutrons. Semen samples were exposed to 0.5, 1.0 and 2.0 Gy of 60Co gamma-rays at 1.7 cGy/ min and 0.25, 0.5 and 1.0 Gy of 252Cf radiation at 1.3-1.7 cGy/ min. In the 60Co experiment, 509 spermatozoa from controls and 902 spermatozoa from the irradiated groups were karyotyped, while in the 252Cf… CONTINUE READING
