Abstract
A nuclear/radiological threat notification system has been designed, fielded and tested as a component of a military base protection system. This system automatically issues alarm-alert-pass notifications to the command post in real time. These notifications are based on radiation detector messages generated by the detection system and communicated immediately for use as inputs to a decision tree. This tree is implemented in XML format and uses message inputs from NaI gamma and He-3 tube neutron detectors to arrive at a notification decision. For example, if a detector site senses both neutrons and high-energy gammas, an alarm is generated. The industrial soil density/moisture gauge, common in many areas, is an important factor in the decision process. This notification system is successful in fusing sensor data in real time and can be readily expanded to incorporate additional nuclear and non-nuclear data. The resulting reporting to the command post appears to be adequate for non-technical operational personnel.
