Abstract
For the first time the concentration of Cl-36 was determined for soil from the Semipalatinsk Nuclear Test Site (SNTS) in the former Soviet Union. Meas urement was performed by liquid scintillation counting (LSC) after radioche mical isolation of the nuclide. Development of the radiochemical separation procedure and choice of scintillation cocktail for low level Cl-36 measure ment was carried out. The concentration of Cl-36 in the sample was determin ed as 1.5 +/-0.2 mBq/g-soil. The obtained Cl-36 concentration is in good ag reement with that estimated using neutron fluence evaluated by gamma -spect rometry of Co-60 and Eu-152.154.
