title: Determination of uranium isotopes by chemical stripping and alpha-spectrometry.
abstract: We describe a new method of preparing thin sources for the determination of uranium isotopes by alpha-spectrometry. The sources are produced by extracting the uranium isotopes from 1 M HNO3-4M Al(NO3)3 aqueous solution with polymeric membranes containing trioctylphosphine oxide (TOPO). We demonstrated that the sources are comparable to those obtained by electrochemical procedures using platinum or stainless-steel cathodes.
