By the Law of Belorus, the annual effective dose is one of the principal indicators used to justify measures on public protection from additional radiation exposure after the Chernobyl accident. To calculate the annual effective dose the approach is used under which the main starting parameters is average dose rate on the territory of a populated point and a daily diet, equivalent to intake of radiocesium with 0.9 l of milk and 0.8 kg of potato per day and intake of Sr-90 with 0.85 l of milk and 0.95 kg of potatoes. The selected methodological approach has enabled estimation of the annual effective dose with a fairly small uncertainty factor (3-5).
