24 EFFECTS OF IONIZING RADIATION References Summary and Conclusions Tue Cunicat Finpines in a population acci- dentally irradiated by fallout material from a nuclear device has been presented. The more seriously irradiated individuals had initial symptoms of anorexia, vomiting and diarrhea which subsided without treatment within 2 days. The same individuals slowly developed granulocytopenia and thrombocytopenia unas- sociated with secondary complications. The only other manifestations of radiation exposure observed were skin lesions and epilation, described in detailin Chapter ITI. The incidence of infectious and noninfectious disease in the more severely exposed groups was no greater than that in the least exposed group. If. after irradiation, the platelets and leukocytes fall in 2% manner and to a degree similar to that observed here, it can be predicted that no hemorrhage or increased susceptibility to diseases similar to those observed in this study will occur .
