Fetal squirrel monkeys of Bolivian and Colombian origin were exposed to 100 rad cobalt-60 radiation in utero and carried to term by the dams. Body weight, head circumference, crown-rump length, and food intake were measured during the first 28 postnatal days. Significant subspecies differences were noted in both mothers and offspring, the Colombian squirrel monkeys being generally larger than the Bolivians. The irradiated offspring weighed significantly less, had significantly smaller crania, and consumed significantly less food than control animals. A statistically nonsignificant decrement was also evident in the crown-rump length of radiation-treated infants.
玻利维亚和哥伦比亚来源的胎儿松鼠猴在子宫内接受 100 拉德钴-60 辐射，并由母体孕育至足月。在出生后的前 28 天，测量了体重、头围、冠臀长和食物摄入量。在母猴和幼猴中都观察到了显著的亚种差异，哥伦比亚松鼠猴通常比玻利维亚松鼠猴更大。受照射的幼猴体重明显较轻，颅骨明显较小，并且比对照动物消耗的食物明显较少。受照射婴儿的头臀长也出现了统计学上无显著意义的减少。
