J. Solecki et S. Chibowski, Studies of soil samples mineralization conditions preceding the determination of Sr-90, J RAD NUCL, 247(1), 2001, pp. 165-169
Some results of the extraction of strontium and yttrium from soil samples b
y concentrated nitric acid are described. The concentration of Sr and Y in
the solid was determined by XRF method. The results obtained allowed to ela
borate the conditions of acid leaching and to propose an analytical procedu
re for the determination of Sr-90 in samples without their total dissolutio
