Abstract:
1. A system for determining a location of a radioactive source, comprising: a detector array comprising a plurality of detectors disposed in a predetermined fixed arrangement wherein at a first time a first of said plural detectors is disposed between a second of said plural detectors and a radioactive source and, due to relative motion between said detector array and the radioactive source, at a second time said first detector is not disposed between said second detector and the radioactive source; and a data system operatively connected to each of said plurality of detectors, said data system comprising: an input system which receives from each one of said plural detectors a signal representative of a number of radioactive particles from the radioactive source detected by the respective one detector; an analysis system which compares the signals received from said each one of the plural detectors; and a locating system which determines a location of the radioactive source based at least in part on the comparison of the signals.
