DETERMINATION OF THE RATIO OF TOTAL TRANSURANICS TO AMERICIUM IN SOIL ON ISLAND DAISY DOE/ERSP TECH NOTENO.2.12 DATED: April 1978 AUTHOR:B. Friesen, DRI Determination of one mean ratio for Daisy was made using laboratory results from soil samples taken at four locations including two composites and three depths. Reference Tech Note 2.2-A for assumptions made in computing the mean ratio and associated error. The range of values is from 2.66 to 9.22. The ratios are as listed below. The Daisy data has a mean ratio of 3.72 with a standard deviation of 0.56*; these values were used in estimating total transuranies and upper bounds.
