Latest Patents

Marie H. Putnam holds a patent for a method of photon spectral analysis. This spectroscopic method allows for the rapid measurement of plutonium presence in soils, filters, smears, and glass waste forms. The technique measures uranium L-shell x-ray emissions associated with plutonium decay. Additionally, it can simultaneously acquire spectra of samples and analyze them for americium and gamma-ray emitting activation and fission products. The method utilizes a large area, thin-window, n-type germanium spectrometer, which is efficient for detecting both low-energy x-rays (10-2000 keV) and high-energy gamma rays (>1 MeV). A sophisticated analyzer captures the entire photon spectrum at once, enhancing the accuracy and efficiency of the analysis.
