Prospects of research works on radiation ecology problem in Kazakhstan

In paper radioecological researches status on Kazakhstan territory are discussed. Mainly radioecological investigations are carrying out at the institutes of National Nuclear Center of Republic of Kazakhstan. At present the radioecological investigations are concentrated on the territory of Semipalatinsk test site (STS) and places where hydrocarbon ores are mining (West Kazakhstan oil fields and Kara-Zhyra coal deposit on territory STS). In these examinations the main attention are paid to problems, related with the particular objects: 1) water (contamination by different radionuclides, radionuclide migration); 2) plutonium (soil contamination on the STS territory); 3) hydrocarbon fuels (contamination with different radionuclides): radon (determination of radon background of the total country territory)
