Post Chernobyl Hemoblastoses in the Republic of Belarus (brief communication).

Data on the incidence of acute leukemia (AL) in children in the Byelorus Republic is analysed and comparisons made between the incidence of AL prior and subsequent to the Chernobyl accident in 1986. The Byelorus Republic was directly and heavily contaminated at that time and careful records of the incidence of cases of AL and other malignancies have since been kept. Byelorus is divided into large administrative regions-oblasts-which are subdivided into raions.
