A coincidence signature library for multicoincidence radionuclide analysis systems

摘要: Pacific Northwest National Laboratory (PNNL), Richland, WA, is currently developing multicoincidence systems to perform trace radionuclide analysis at or near the sample collection point for applications that include emergency response, nuclear forensics, and environmental monitoring. Quantifying concentrations with these requires a library of accurate emission intensities each detected signature, all candidate radionuclides. While such data are readily available single gamma-ray emissions, no signature has been found coincident emissions as /spl beta/-/spl gamma/, gamma/-/spl gamma/. To meet this need, Coincidence Lookup Library (CLL) being developed calculate signatures from user-specified radionuclide, conversely, determine radionuclides may be responsible specific signature. The algorithms used generate absolute various user interfaces developmental CLL described.
