Results are reponted from experimental tests for recovery systems that act after radiobiological damage and studies on the types of genetic damage induced and the recovery of mutational types of damage from spermatogonial cells of Drosophila virilis. Dose rate studies with gamma rays in anoxic and oxygenated atmospheres were employed in investigations of postirradiation methods for reducing genetic damage. Higher values for dominant lethals were recovered from spermatogonia after irradiations with 22-Mv x rays than with 200-kv x rays. Investigations were made of chromosome breakage, cell degeneration, genetic damage, and mutational studies of sex-linked and autosomal loci. Direct comparisons were made of loci on the sex chromosome and the autosomal loci in sperm and spermatogonial cells. (C.H.)
