	234U/235U act ratio = 22.012 +9.372(LOG wt% 235U) -3.516(LOG wt%
235U)^2

	IN:
	Rucker and Johnson Jr. 'relationship between isotopic uranium
activities and total uranium at various uranium enrichments'  J. of
Radioanalytical and Nuclear Chemistry 235 (1-2) (1998) 47-52.

	There are other equations given also.  Make sure you use the
equations from the figures, not the text, as there are several misprints.
