OSTI ID:4043345
Gamma irradiation of drosophila sperm and spermatide by 5 r induces recessive lethal mutations. Fractionated irradiation with 20 r, at 5 r per exposure at 1.5 hours intervals, resulted in cumulative mutagenic effects. Identi cal doses of fast neutrons produced 1.5 to 2-fold higher mutagenic effects. The spermatide mutability resulting from exposure to fast neutrons and gamma radiation is two-fold stronger than in sperm. Experiments with doses up to 5 r indicate no thresholds for the mutagenic effect. (R.V.J.)
