A Si(Li) planar detector provides sufficient photopeak resolution to resolve the 20.16-keV U L gamma x rays resulting from /sup 239/Pu decay and the 20.78-keV Np L gamma x rays resulting from /sup 241/Am decay. The energies and, therefore, the absorption coefficients of the two x rays are very similar; thus, the ratio of the peaks for a source embedded in tissue remains approximately the same for the two x rays up to at least 6 mm. Measurements of /sup 239/Pu-to-/sup 241/Am ratios by this method in deep wounds agree with results obtained by radiochemical analysis of excised tissue.
