Summary

Hamsters pregnant with 6.5- or 7.5-day embryos were exposed to single and fractionated doses of gamma radiation ranging from 25 to 200 r. The threshold for mortality of 6.5-day embnyos was about 75 r and of 7.5-day embryos was about 100 r. The percentage of abnormal fetuses increased from 5 to 100% following irradiation of either 6.5or 7.5-day embnyos with either single or fractionated doses over the range of 50 to 200 r. The development of pathological manifestation in relation to dose is discussed. (C.H.)
