For the first time the concentration of 36 Cl was determined for soilfrom the Semipalatinsk Nuclear Test Site (SNTS) in the former Soviet Union.Measurement was performed by liquid scintillation counting (LSC) after radiochemicalisolation of the nuclide. Development of the radiochemical separation procedureand choice of scintillation cocktail for low level 36 Cl measurement was carriedout. The concentration of 36 Cl in the sample was determined as 1.50.2 mBq/g-soil.The obtained 36 Cl concentration is in good agreement with that estimatedusing neutron fluence evaluated by . -spectrometry of 60 Co and 152,154 Eu.
