%X A radiochemical method for simultaneous determination of U, Th and (228)Ra in sediments and biomass was investigated. The sensitivities of the method were 10(-6)g for U and Th and 17.7Bq/kg for (226)Ra respectively. Radiochemical recovery of (226)Ra was 81.7%, while chemical recovery of Ba was 90.7%. The decontamination of the method was satisfactory.
