Optimization of a new radiochemical method based on extraction chromatographic resins and plastic scintillation for measurement of <sup>90</sup>Sr in nuclear waste

A purification method is developed to determine <sup>90</sup>Sr in radioactive waste. A separation based on Sr-resin® with a pretreatment using TRU-resin® provides satisfactory Sr recovery yields before the <sup>90</sup>Sr measurement by liquid...
