Determination of the
36 Cl and129 I massic activities using pyrolysis combined with radiochemical separation (using a Cl-resin) in concrete and graphite samples from decommissioning waste originating from Belgian Reactor 3 and 1 (SCK CEN, Belgium), respectively, is described. Liquid scintillation counting is used for their quantification. The chemical recovery of the procedure was evaluated by determining the stable chlorine with ion chromatography and stable iodine with inductively coupled plasma mass spectrometry. The method was optimized and verified by spiking inactive solid materials. [ABSTRACT FROM AUTHOR]- Published
