ALIQUOT SIZE (w) IN GRAMS
Figure 3.
Estimated Values of the Variance of Average Am
Ge(Li) Scans as a Function of Aliquot Size for
a Composite Soil Sample Collected Approximately
150 ft North of GZ at NS-201.
The cost equation relating the cost in dollars for Pu wet chemistry
analysis of n aliquots of size w is assumed here to be given by
C = n(83 + 1.8 w).
(12)
This gives a range in cost per aliquot of from $85 to $263 for aliquots
between 1 and 100 g.
Solving Equation 12 for n gives
