Performance of a neutron-sensitive scintillating glass fiber panel for portal, freight, and vehicle monitoring

Neutron-sensitive scintillating glass fiber sensors provide several advantages over 3 He and BF 3 gas-tubes for plutonium detection and surveillance. Large active areas provide significant improvements in sensitivity versus cost. In addition, the glass sensors offer a wide dynamic counting range, fast response time, and low microphonic susceptibility relative to conventional sensors. We report the results of detection limits for neutron glass panels used for portal, freight and vehicle monitoring.
