Results are reported from studies on the effects of radiation dose rates on genetic damage in mature sperm and various types of germ cells of the spermatogenic cycle in Drosophila virilis. The cells were exposed to fission neutrons, accelerator neutrons, and ionizing radiations from therapy x rays, gamma rays from a Co/sup 60/ source, and 22Mv x rays from a betatron accelerator in anoxic atmospheres afforded by nitrogen and argon and in gaseous atmospheres containing oxygen. Tests were made for genetic mutations at specific gene loci in sperm and spermatogonial cells. Differences in radiation damage after treatment of mature germ cells and premeiotic spermatogonial cells are discussed. Preliminary results are included from a study of possible mechanisms for retention of radiation induced mutations in gene populations in Drosophila, (C.H.)
