Abstract

New process to determine $^{90}Sr$ in the environmental samples was established by investigating the existing methods. The environmental samples included soil, milk, seaweed, fishes and clams, pine needles, and marine sediment. Using the developed method combined with fuming nitric acid and ion exchange resin, which could be reduced the treatment step, we could be removed Ca effectively for the determination of $^{90}Sr$. The recovery yield of $^{90}Sr$ in this method was 10% higher than those of using the fuming nitric acid only. This method could be applied to all environmental samples we choose. The content of $^{90}Sr$ in soil was the highest value in the tested environmental samples.
