The hematopoietic syndrome results from acute whole-body doses above 200 rads. A prodromal phase consists of nausea and vomiting within the first 12 hrs, with symptoms usually lasting up to 48 hrs. A latent period of 2-3 wks during which patients may feel quite well follows. Although patients are asymptomatic, bone marrow impairment has occurred. The most obvious laboratory finding is lymphocyte depression.
