DETERMINATION OF THE RATIO OF TOTAL TRANSURANICS TO AMERICIUM IN SOIL ON ISLAND KATE DOE/ERSP TECH NOTENO. 2.10 DATED: March 1978 AUTHOR: J. Giacomini, DRI Determination of one mean ratio for Kate 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 2.34 to 3.37. The ratios are as listed below. The Kate data has a mean ratio of 2.7 with a standard deviation of 0.13*; these values were used in estimating total transuranics and upper bounds.

Giacomini, DRI Determination of one mean ratio for Nancy 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 2.32 to 3.94. The ratios are as listed below. The Nancy data has a mean ratio of 2.7 with a standard deviation of 0.18*; these values were used in estimating total transuranics and upper bounds.
