title: An improved radiochemical procedure for low-level measurements of americium in environmental matrices.
abstract: The chemical yield and accuracy of measurements of (241)Am at low levels in marine environmental matrices have been substantially improved by applying the extraction procedure with DDCP (dibutyl-N,N-diethylcarbamylphosphonate). The improved procedure is described, and its advantages over the conventional procedure are discussed.
