Method and apparatus for detection of radioactive material
First Claim
1. A radioactive material detection system comprising:
- a plurality of radioactive material detection apparatuses, each apparatus being disposed in or on a cargo receptacle and each apparatus comprising;
a wireless transmitter capable of wirelessly transmitting information in correspondence with a signal;
a radiation sensor having a sensor output, the radiation sensor being configured to detect radiation over a predetermined or commanded period of time; and
a detection controller configured to receive the sensor output from the radiation sensor and to send the signal to the wireless transmitter for transmission; and
a master unit/master module comprising;
a receiver configured to receive the wirelessly transmitted information from each of the wireless transmitters of the plurality of radioactive material detection apparatuses; and
a master controller coupled to the receiver, the system being configured to detect 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 and (ii) comparing the current measured radiation at each radioactive material detection apparatus location to the initial average measured radiation level at each location in order to identify an anomaly amongst the plurality of cargo receptacles.

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.

13. A radioactive material detection system comprising:
-
a plurality of radioactive material detection apparatuses arranged in or on an object to be tested, each apparatus comprising;
a wireless transmitter capable of wirelessly transmitting information in correspondence with a signal;
a radiation sensor having a sensor output, the radiation sensor being configured to detect radiation over a predetermined or commanded period of time;
a detection controller configured to receive the sensor output from the radiation sensor and to send the signal to the wireless transmitter for transmission; and
an identification tag electrically coupled to one of the controller and the wireless transmitter, the identification tag being configured to provide identification data or location data to the information being transmitted by the wireless transmitter; and
a master unit/master module comprising;
a receiver configured to receive the wirelessly transmitted information from each of the wireless transmitters of the plurality of radioactive material detection apparatuses; and
a master controller coupled to the receiver, the system being configured to detect fissile or nuclear material that emits radiation within the object to be tested and to use location data from the plurality of radioactive material detection apparatuses to determine a location of the fissile or nuclear material within the object to be tested.
