Abstract
Absorption-edge densitometry is a matrix independent, nondestructive assay (NDA) technique that is being developed to measure special nuclear materials (SNM) in a variety of chemical compositions. In addition to being well suited for use in assaying SNM in solution, this technique is proving applicable to various solids including plutonium-bearing ash and MTR fuel bundles. Accuracies of 0.5-1% are easily attainable for SNM concentrations , 04
