Some radiochemical analytical methods for the determination of important beta-radionuclides for decommissioning are presented. An analytical method is briefly described, which is used for the determination of 3H and 14C in steel and aluminum by combustion using commercial oxidizer. A leaching method was developed for the determination of 3H in the contaminated silica gel.
A simple distillation method is presented for the determination of 14C in heavy water and wastewater sample. A method developed for the simultaneous determination of 3H, 14C, 36Cl, 55Fe, 63Ni, 41Ca and 129I in concrete, graphite, aluminium, lead, and steel is presented. The developed methods have been successfully used to analyse various materials for characterization of the waste during the decommissioning of Danish nuclear reactors.
