OSTI ID:4670075
>The results of studies on the genetic effects of radiation on Drosophila melanogaster are brieily summarized. The relative radiosensitivity of several stages of germ cell development to gamma and x rays and neutrons was determined. The results lend support to the view that the extreme radiosensitivity of spermatids is in large measure due to the presence of relatively high amounts of oxygen in such cells. It was found that x irradiation in air or 100% oxygen and neutron irradiation of spermatozoa yields mostly whole- body mutations (80%), while x irradiation in 100% nitrogen or 100% helium yields fewer whole-body mutations (35%).
