Summary  

The results of radioecological investigations in the Syrdarya river basin in the Republic of Kazakhstan are presented. The work was carried out under the International Navruz Project. Nuclear activation analysis, X-ray fluorescence, and &-spectrometry were used to measure the element and radionuclide (137Cs, 40K and 238U, 235U, and 232 Th families) compositions of soil, water, bottom sediments and vegetation. Samples were collected at 15 control points in Kazakhstan along the Syrdarya river and its inflows during four expeditions (autumn 2000 and 2001, spring 2001 and 2002).
