Abstract
The research and engineering operations performed to clean and remove
radioactive contamination from the Azgir test site improved levels of radiation in
and around the site. After the operations, the possibility of contamination of
personnel and the local population from radiation doses in the soil that exceed
maximal permissible values for radiation were eliminated.
Keywords: Azgir nuclear test site, underground nuclear explosions,
radionuclides, underground cavities from nuclear explosion, radioactive wastes.
1 Introduction
At the present time there are problems as a result of controlled peaceful nuclear
explosions in Kazakhstan, which include clean-up activities in the contaminated
area where the nuclear explosions were conducted. A considerable amount of
time has passed since the explosions were carried out. This report addresses
problems such as the removal of contaminated soil from the former AZGIR test
site in the west of Kazakhstan. The pilot research was carried out from 1964 to
1979 by means of underground nuclear explosions in the rock salt massifs of an
underground cavity used for multifunctional storage near to Azgir in Atyrau
oblast (250 km from Caspian Sea and 70 km from the Volga River) at the salt
dome of East and West Azgir. Among 39 peaceful underground explosions
conducted in Kazakhstan (Table 1, Figure 1) [1], 17 explosions (22 blasting
charges with energy release in trinitrotoluol equivalent from 0.01–103kt) were
carried out at a depth of 160–1500m at 10 sites of the Azgir test site (Table 2).
The total activity of underground cavities is about 106 Ci [2,3].
Keywords
Azgir nuclear test site, underground nuclear explosions,
radionuclides, underground cavities from nuclear explosion, radioactive wastes.
