| | PDF (873 KB) | HTML

The energy spectra of gamma-rays emitted by radioisotopes act as finger prints that enable identification of the source. Such identification from low-resolution NaI detectors over short time periods is challenging for several reasons, including the Poisson fluctuations in the recorded counts. Smoothing the data over neighboring energy bins can reduce the noise in the raw counts, at the cost of int... View full abstract»

Abstract-The Alpha-activity resulting from the presence of actinides inside nuclear waste packages must be characterized, in order to select the most appropriate means of storage. Non-destructive active methods, based on the fission process, allow the global mass of actinides to be quantified.
