Laboratory hematological data of children and adolescents living at Kaluga region territories contaminated with radionuclides and of liquidators were analyzed. Over 50.000 hemograms were analyzed over 1986 to 1993. Analysis of a vast data scope in the register helped detect the most essential and incident disorders in the hemograms. These abnormalities are reduced count of red cells often associated with macrocytosis, leuko - and lymphocytopenia in children, leukocytosis and lymphocytosis in adolescents and adults, morphological signs of disordered immunocompetent system of the blood.
