Radiation Monitoring of Public Exposure After the Chernobyl Accident

A. Nikalayenka (Scientific Practical Center of Hygiene of the Ministry of Health, Belarus)

On the early post-accidental stage after Chernobyl accident the remediation activity in the contaminated areas was firstly aimed at guarantee that the foodstuff produced in the contaminated areas werewithin the republican permissible levels (RPL), andannual effective dose to local inhabitants was lower than 1 mSv/a.

The paper presents studies of this evolution process based on theanalysis of consumption and radioactive contamination of locally products and permanent assessment ofpopulation doses. The studies show the reasonability to use a graded approach to radiation control requirements, which are to be selective for different groups of the contaminated localities depending on their location, average public exposure dose, and density of radionuclide contamination. It is emphasized, that in the existing exposure situation the radiation monitoringon the contaminated areas is preferable than by the radiation monitoring accordance with RPL.

チェルノブイリ事故後の早期事故後段階では、汚染地域における修復活動はまず汚染地域で生産された食品が共和国の許容レベル(RPL)内にあり、地域住民の年間実効線量が1 mSv/年未満であることを保証することを目的としていた。本書では、地元の産物の消費と放射能汚染の分析、及び集団線量の永続的な評価に基づいて、この進展の過程についての調査を紹介する。この調査では、汚染地域の位置、平均公衆被ばく線量、及び放射性核種汚染の密度に応じて、汚染地域の異なる集団に対して選択的である放射線管理要件に対する段階的アプローチを使用することの合理性が示される。現在の被ばく状況では、汚染地域の放射線モニタリングの方がRPLに基づく放射線モニタリングよりも望ましいことが強調されている。
