Abstract
A pre-concentration method for Cs-137 from large water samples was dev eloped. The method allows an in-situ pre-concentration of 100-liter wa ter samples in less than 1 h and is based on the percolation of the sa mples through a column containing Prussian blue impregnated ion-exchan ge resin. The method was applied in Goiania, Brazil, site of a radiolo gical accident in 1987, in order to evaluate the contamination of grou nd and surface waters. The average chemical yield was (70 +/- 4) % and Cs-137 concentrations ranging from 1.7 to 105 mBq liter-1 were found.
