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 417
