Abstract
In this paper, DGA-normal resin has been used for the chemical separation of Sr and Y from Cs as well as other elements in standard solutions. The decontamination factor of Cs was tested in different acidic media. It was found that 8 M HNO3 was the most effective rinsing solution with a Cs decontamination factor exceeding 400,000. Application of the DGA-normal resin allows the separation of Y and Sr from other interfering beta emitter isotopes. This resin is suitable for 90Sr and 90Y separation in contaminated Fukushima soil samples giving the prospect of 90Sr measurement in a direct (90Sr) and indirect way (90Y).
