Emesis data from 41 rhesus monkeys exposed to radiation doses between 2050 and 4500 rads neutron-gamma ratio 3.0 were analyzed and compared with corresponding data from 129 rhesus monkeys exposed to doses between 700 and 5600 rads neutron-gamma ratio 0.4. There were no statistically significant differences in the time course of vomitions or in the incidence of vomiting with dose. In those animals that did vomit, the frequency of vomiting was greater in the aminals exposed to the predominantly neutron field.
