5. Conclusions A procedure is presented for the extraction and analysis of total strontium-90 in soil. Available evidence shows it to be highly efficient as campared to the fusion technique for most soils and certainly more effective than other extraction methods. From an analytical standpoint, the precision is adequate and the limiting factor in the determination is the error due to sampling. ‘The importance of site Selection and sampling technique cannot be over-emphasized. The purpose of this report, however, is not to evaluate soil sampling seemee eo os entire eee cteT enA a em eee ee put rather the analytical procedures involved. r o DS) « =.
