DETERMINATION OF THE RATIO OF TOTAL TRANSURANICS TO AMERICIUM IN SOIL ON ISLAND WILMA DOE/ERSP TECH NOTE NO. 2.14 DATED: April 1978 AUTHOR: B. Friesen, DRI Determination of one mean ratio for Wilma was made using laboratory results from soil samples taken at four locations including two composites and two depths. Reference Tech Note 2.2-A for assumptions made in computing the mean ratio and associated error. 2.43 to 4.50. The ratios are as listed below. The range of values is from The Wilma data has a mean ratio of 2.73 with a standard deviation of 0.19*; these values were used in computing total transuranics. Estimates and upper bounds were not computed because of insufficient data; indicated 24lam concentrations do not warrant collection of more data.

Friesen, DRI Determination of one mean ratio for Mary was made using laboratory results from soil samples taken at five locations including two composites and three depths. Reference Tech Note 2.2-A for assumptions made in computing the mean ratio and associated error. 2.33 to 6.09. The ratios are as listed below. The range of values is from The Mary data has a mean ratio of 2.94 with a standard deviation of 0.42*; these values were used in computing total transuranics.
