Patent ID: 6965314

Claim:
A radioactive material detection system comprising: a cargo container monitoring system including: a plurality of radioactive material detection apparatuses having a wireless transmitter, a radiation sensor configured to detect radiation over a predetermined or commanded period of time, a detection controller configured to send sensed radiation to the wireless transmitter for transmission and an identification tag electrically coupled to one of the controller and the wireless transmitter and configured to provide identification data or location data to the information being transmitted by the wireless transmitter; and a master unit/master module having a receiver configured to receive the wirelessly transmitted information from each of the wireless transmitters of the plurality of radioactive material detection apparatuses, a transceiver and a master controller coupled to the receiver and configured to send the information received from the radioactive material detection apparatuses through the transceiver; and a control center in communication with the transceiver of the master unit/master module, the control center being configured to receive data from at least one additional source other than the master unit/master module and to asynchronously analyze the data from the at least one additional source and the information from the radioactive material detection apparatuses so as to detect radioactive material in a particular container.
