Overall recovery of the carrier strontium for the three levels is low for the 72% HNO,. The acid volume is also significant for precipitate weight, and the combination of 78% HNO, at small volume gives very high precipitate weight. This is in agreement with the Sr®° recovery results which showed low activity because of self-absorption. ke? 5/ UNCLASSIFIED
