From effects of neutron irradiation upon cell function; Neuherberg, F. R. Germany (22 Oct 1973). Seeds of maize were exposed to x rays at a dose rate of 1658 to 1845 rad/min; other seeds were exposed to fission neutrons at a dose rate of 27.5 to 198 rad/min. The irradiated seeds and controls were sown in moist soil. When mature the fourth and fifth seedling leaves were harvested and scored for frequency of yellow-green sectors. Tables and graphs are presented to show dose-response data for frequency of yellow-green sectors per leaf, frequency of mutations as a function of absorbed dose, neutron-induced yield of mutations and RBE of neutrons in comparison to x radiation.
