[Assessment of the immunohematological status of children exposed to low doses of ionizing radiation in the early and late periods after the Chernobyl AES accident].

The qualitative and quantitative parameters of hemopoiesis and immunocompetent cells were studied in 365 children in the early "iodine" and long-term periods after the accident. In accordance with primary response, a group consisting of 28 subjects with so-called "radiation injury" was distinguished. The early period was marked by unusual qualitative and quantitative hematological changes which, however, did not lead to the development of the hematological syndrome characteristic of acute radiation injury. Certain deviations that corresponded to somatic pathology were detectable at the late periods after the accident.
