Strategy for population protection and area rehabilitation in Russia in the remote period after the Chernobyl accident.

The report presents the history of the development of criteria for radiation and social protection of the Russian population residing in the areas contaminated with radionuclides after the Chernobyl accident, in the remote time periods after the accident. The tendencies for reduction of standards with time are shown, and their causes are analysed. It is noted that the optimization principle was not applied in the explicit form for population protection. The current radiation situation in the contaminated areas of Russia is described, and the future situation is forecast. Main pathways of external and internal population exposure are described. Modern possibilities for reduction of the population exposure dose are discussed. The authors propose promising criteria and methods for population protection and rehabilitation of contaminated areas in Russia.
