Abstract
Hybrid Kedge densitometry HKED is a nondestructive analytical assay technique used to provide rapid determination of actinide concentration in tank solutions Of special interest for HKED is the estimation along with associated uncertainties of the ratio of the flouresence yeilds ω K of uranium and plutonium Limited experimental data for ω KZ as a function of atomic number Z exist and the data are subject to experimental uncertainty Previous studies have provided values for ω KZ with uncertainty estimates but have not included covariance information We use a phenomenological model with a bootstrapping method to generate the ratio ω K94/ω K92 and associated uncertainty
