Abstrakt: Abstract: A new method has been developed for the separation and determination of low-level activity of strontium-90 through its daughter product yttrium-90 from natural water. Yttrium was separated and isolated from 1001 water at pH 5.5–5.7 by 8-quinolinol substituted silica gel. The yttrium was eluted with hydrochloric acid and precipitated with ammonium oxalate. The precipitate of yttrium oxalate was counted with a low-background beta-counter. The recovery of yttrium-90 is (64±4)% (n=5).
