ON INFLUENCE OF THE UNDERGROUND NUCLEAR EXPLOSIONS CRYSTAL AND KRATON-3 ON RADIOLOGICAL SITUATION IN THE NEAREST SETTLEMENTS

The results of radiological investigations (in 2001-2002) conducted near sites of the underground nuclear explosions Crystal and Kraton-3 in the Republic of Sakha (Yakutia) are presented. The sum of the current effective internal doses from 137Cs and 90Sr (from consumption of natural products) and t...

Description
Summary:The results of radiological investigations (in 2001-2002) conducted near sites of the underground nuclear explosions Crystal and Kraton-3 in the Republic of Sakha (Yakutia) are presented. The sum of the current effective internal doses from 137Cs and 90Sr (from consumption of natural products) and the external dose from 137Cs deposition was about 21 μSv y-1 for adult residents of the urban settlements Aihal and Udachny. Intake of 137Cs and 90Sr (originating from global fallout) with reindeer meat contributes ~87% to the internal dose determined. At present, the consequences of the underground nuclear explosions, conducted in the 1970s, have no influence on the technogenic exposure of the local population.
