Alexander, M L

The effects of radiation on the genetic system of organisms in relation to their physiological and biochemical systems were investigated in the immature germ cells of Drosophila virilis. This biological system offers a group of cells composed of spermatogonial cells, meiotic cells, and post-meiotic spermatid and sperm cells. Different amounts and types of biological damage were observed in the different types of cells. Results are presented on the effects of fast neutrons, 200 kv x rays, 1.17- to 1.33-Mev gamma rays from a Co/sup 60/ source, and 22-Mev x rays from a betatron source. The relative biological efficiency values for the radiations used were calculated using the rad dose necessary to produce lethals in 50 percent of the cells. Data are tabulated. (C.H.)
