DETERMINATION OF THE RATIO OF TOTAL TRANSURANICS TO AMERICIUM IN SOIL ON ISLAND BELLE DOE/ERSP TECH NOTE NO. 2.8 DATED: March 1978 AUTHOR: J. Giacomini, DRI Determination of one mean ratio for Belle 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. The range of values is from 3.09 to 5.82. The ratios are listed below. The Belle data has a mean ratio of 3.8 with a standard deviation of 0.42*; these values were used in estimating total transuranics and upper bounds.

Giacomini, DRI B. Friesen, DRI Determination of one mean ratio for Clara 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 2.94 to 7.92. The ratios are listed below. The Clara data has a mean ratio of 4.23 with a standard deviation of 0.98*; these values were used in estimating total transuranies and upper bounds.
