Abstract:
A radioactive material detection system includes a plurality of radioactive material detection apparatuses and a master unit/master module. Each apparatus is disposed in or on a cargo receptacle and each apparatus has a wireless transmitter, a radiation sensor and a detection controller. The master unit/master module has a receiver configured to receive the wirelessly transmitted information from each of the wireless transmitters and a master controller. The system detects fissile or nuclear material that emits radiation by (i) calculating and storing at the master unit/master module an initial average measured radiation level at each radioactive material detection apparatus location throughout the entire array of radioactive material detection apparatuses and (ii) comparing the current measured radiation at each radioactive material detection apparatus location to the initial radiation level at each location in order to identify an anomaly amongst the plurality of cargo receptacles.
Abstract:
A radioactive material detection system (200) includes a cargo container monitoring system (10) and a control center (220). The cargo container monitoring system (10) has a radiation sensor (24) configured to detect radiation over a predetermined or commanded period of time and a transceiver (26) configured to send the information received from the radiation sensor (24). The control center (220) is in communication with the transceiver of the cargo container monitoring system (10). The control center (220) is configured to receive data from at least one additional source (222) other than the cargo container monitoring system (10) and to asynchronously analyze the data from the at least one additional source (222) and the information from the radiation sensor (24), during transit, so as to detect radioactive material in a cargo container (12).

Abstract:
A radioactive material detection apparatus (20) includes a transmitter (26), a radiation sensor (24) and a controller (30). The transmitter (26) is capable of transmitting information in correspondence with a signal. The radiation sensor (24) has a sensor output and is configured to detect radiation over a predetermined period of time. The controller (30) is configured to receive the sensor output from the radiation sensor (24) and to send the signal to the transmitter (26) for transmission.
