Popis: A method for the determination of radium in environmental water by means of a liquid scintillation counting technique has been developed. The radium was collected on cation exchange resin with 100% recovery by the batch method. The other radionuclides except uncomplexed elements such as cesium can be removed by washing the resin with 0.01 M EDTA solution at pH 8. The counting sample was prepared by immersing the resin into emulsion liquid scintillator in a Teflon vial. The chemical procedure took about 2 h and the detection limit was 0.03 pCl of /sup 226/Ra/L.
