METHOD AND APPARATUS FOR DETECTION OF RADIOACTIVE MATERIAL

摘要

A radioactive material detection system (200) includes a plurality of radioactive material detection apparatuses (20) and a command center (220). Each apparatus (20) is disposed in or on a cargo receptacle (12). Each apparatus (20) includes a wireless transmitter (20), a radiation sensor (24), a detection controller (30) and an identification tag (28, 32). The radiation sensor (24) is configured to detect radiation over a predetermined or commanded period of time. The command center (220) is configured to receive the wirelessly transmitted information directly or indirectly from each of the wireless transmitters (26) of the plurality of radioactive material detection apparatuses (20). The system (200) is configured to detect fissile or nuclear material that emits radiation. The system (200) is reconfigurable from a passive sensing system to an at least partially active sensing system in the event that the system (200) detects a nuclear anomaly within a cargo receptacle.
