Abstract:

High-resolution alpha particle and photon spectroscopy is applied to determining the ratios of 239Pu and 240Pu in isotopically mixed samples of less than a few thousand DPM. The utility of alpha-gamma coincidence and L-shell x-ray spectroscopy methods are explored. Experimental equipment, procedures and calibration methods are discussed. Minimum sample activities necessary for quantification are presented for each method. Instrumental and statistical uncertainties prevented reliable determination of isotopic ratios. Improvements in equipment are recommended to reduce uncertainties. Author
