Nuclide decay discriminator system and method

摘要

A nuclide decay discriminator system and method is disclosed. The system utilizes a digital computing device (DCD) to capture radiation counts from a radiation detection device (RDD) such as a photon detector via the use of one or more integrated analog-to-digital converters (ADC). The radiation count information is then processed using a recursive procedure in the DCD that determines the desired nuclide to be evaluated and then defines the possible nuclide decay transition states. For each possible nuclide decay state, a recursive permutation of possible state transitions from this nuclide state is determined using a state permutation engine (SPE). Combinations of these state transition branches are linked to form state transition chains each having individual probabilities associated with the overall state transition chain. These state transition chain probabilities are applied to the RDD ADC data to form observed RDD radiation data radiation count probabilities and displayed in real-time.
