Abstract

A detection unit for detecting ionizing radiation including a crystal that interacts with incoming radiation; a processing module that analyzes the incoming radiation detected by the crystal; a positioning module that determines position of the detection unit; and a network interface module that receives and transmits time stamped radiation data and position information from/to a plurality of other detection units. The detection unit automatically identifies other detection units that are located close to form a cluster. The detection unit also includes radiation data integration logic that integrates the incoming radiation data from all detectors in cluster, the position of the detection unit, the received radiation data from other detection units and the received position information from other detection units in real time, and process it simultaneously, that allows significantly improve performance and reliability.
