title: Isotopic composition analysis of dilute Pu solutions using 90-105keV region of gamma ray spectra.
abstract: Isotopic composition of dilute Pu solutions (1-3900μg/mL) has been determined by analysis of HPGe detector response function in the 90-105keV region of gamma ray spectra. Results are in excellent agreement with that obtained from mass spectrometric measurements. The present method has been successfully applied for samples of low Pu concentrations, which otherwise is not possible using the conventional 120-415keV region of plutonium γ ray spectra.
