Abstract

The major factors determining 137Cs dynamics activities in milk and an organism of inhabitants of the contaminated territories in the autumn-winter 1986 after ChNPP accident are estimated. It is shown, that within the first year after ChNPP accident a root way of 137Cs receipt in grass and milk practically unimportant for internal irradiation doses inhabitants. It is established, that within 155 and 200 days after accident for age 1-2 years and more than 10 years inhabitant’s dynamics of 137Cs activity in their body will be determined only by activity 137Cs activity in milk due to superficial pastures grass contamination. At radiometry inhabitants in later times after the stall season beginning a dynamics of in their body will be determined by 137Cs activity in milk due to 137Cs activity first hay crop.

Key words
ChNPP accident, contamination, milk and pasturable vegetation, doses, internal irradiation, inhabitants.
