1. A computerized system for determining location by tracking a source of ionizing radiation, the system comprising:
- at least one first radiation detector capable of receiving ionizing radiation from the source and for producing first output signals;
at least one second radiation detector capable of receiving ionizing radiation from the source and for producing second output signals; and
at least one processor configured to receive and use a pair of said first and second output signals, said pair of said first and second output signals used to determine a plane in which the source resides,wherein said at least one processor is configured to receive and use at least two pairs of said output signals each pair used to determine a respective plane in which the source resides, and is configured to compute an intersection of at least two planes to track the location of the source.

Abstract
A computerized system for locating a device including a sensor module and a processor. A radioactive source, associated with the device, produces a signal in the form of radioactive disintegrations. The sensor module includes a radiation detector capable of receiving a signal from the source attached to the device. The sensor module produces an output signal. The processor receives output signal(s) and translates output into information relating to a position of source.
