Abstract : One hundred and twenty-nine male rhesus monkeys (Macaca mulatta) exposed to prompt radiations (neutron/gamma = 0.4 and pulse width = 50 msec) ranging from 700 to 5600 rads (midhead dose) were analyzed for incidence of vomiting. The animals were fasted 18 hours preexposure and observed for incidence of vomiting for two hours postexposure. For doses less than 1000 rads, the number of animals that vomited increased directly with dose. Above 1000 rads, the number of animals that vomited decreased with increasing dose. The total number of vomitions per dose group followed a nearly identical pattern to the incidence of emesis. In all dose groups most of the emetic episodes occurred between 20 and 50 minutes postirradiation.
