Spectroscopic portal for an adaptable radiation area monitor

摘要

A detection system operating on a scalable Radiation Sensor Unit (RSU) data stream employs a detection module triggering an alarm based on fee dynamic temporal features of gross count. Two spectroscopic buffers, one holding a long-term background and one holding the integrated detection event data are passed on for identification. The detector data incorporates sets of counts measured at channelized gamma energies. Each multi-channel data set is reduced to highly accurate peak locations. The absolute energy of the peaks is determined using innovative techniques and the background peaks and other secondary peaks are eliminated to provide a concise list of corrected source peak locations and intensities. This, together with spectral region analysis results is used with pattern recognition algorithms to identify fee source isotope or combination of isotopes from a standard library.
