Processing of screening data obtained for peripheral blood of children exposed to radiation in Chernobyl accident.

The paper describes processing of peripheral blood screening based on methods of mathematical statistics and partially ordered sets theory. This allows global assay of individual and populational blood, assessment of borderline conditions by introduction of global criterion. The above methodology was tried to analyze data obtained at screening of peripheral blood from children living in radionuclide-contaminated regions. The most considerable contribution to region-specific populational differences belongs to red cells, monocytes, band neutrophils, eosinophils. Hemogram deterioration in children and adolescents seems to result rather from chemical pollution and social factors than radiation effect (in doses not high than 2.2 rem a year).
