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.

DOE/ERSP TECH NOTE NO, 2.13
DATED: April 1978
AUTHOR: B.Friesen, DRI
Determination of one mean ratio for Tilda was made using laboratory results from soil samples
taken at six locations including two composites and three depths. Reference Tech Note 2.2-A for
assumptions made in computing the mean ratio and associated error.

*Due to a programming error, the standard deviation reported here is overestimated.
**One or more of the computational components was less than the minimum detectable activity.
***This one higher ratio had no measurable influence on the mean ratio because the relevant values
were very low.
