At the remote period after the Chernobyl accident problems, which define the adequacy of decision for radiation safety, is a correct evaluation of doses of the population, living in the contaminated areas. A method for assessing the average annual effective internal dose of residents of the settlements located on contaminated territories was developed. The method is based on the classification of settlements according to the regional migration characteristics of soils, population size and forest area around the settlement, as well as the regression dependence of the internal dose calculated on WB-measurements in each class. According to the developed method, a Catalogue of Average Annual Effective Doses of Residents of Belarus has been established. The Catalogue along with the density of soil contamination of the settlements is the basis for next in turn document of the Council of Ministers of Belarus for classification of the settlements by zones of radioactive contamination.

チェルノブイリ事故問題後の避難期間において放射線安全に関する決定の妥当性を判断するのは、汚染地域居住者の線量の適切な評価である。汚染地域にある居住地の住民の平均年間実効内部線量を評価する方法が開発された。この方法は、土壌の地域的な移動特性、人口規模、居住地周辺の森林地域による居住地の分類、並びにクラスごとにWB測定で計算された内部線量の回帰依存に基づいている。開発された方法に従い、ベラルーシ住民における平均年間実効線量の一覧が作成された。この一覧が居住地の土壌汚染密度と共に、放射能汚染区域による居住地の分類に関する今後のベラルーシ閣議文書の基礎となる。
