PROGNOSIS OF DIRECTIONS OF TECHNOGENE RADIONUCLIDES SPACIOUS MIGRATION AT THE TERRITORY OF SEMIPALATINSK TEST SITE AND BEYOND IT

摘要

The present work gives an account of the technogene radionuclides mobility in different types of soils at the Semipalatinsk test site and factors determining them. Weak radionuclides vertical migration is noticed in chestnut and light chestnut soils and more intensive in meadow ones. Ways of radioactive substances migration both on the territory of Semipalatinsk test site and the territory beyond it were revealed. It is general geochemical flow to the north and northwest towards Irtysh river valley. More intensive geochemical flow was noticed from Degelen massif at the east to the upper part of Shagan river valley.
