First Claim
1. A method for determining a direction associated with gamma and/or neutron radiation emissions from a radiation source at stand-off distances, the method comprising:
- receiving from a first detector in a detector set, a first radiation photon count associated with the first detector, wherein the first radiation photon count is associated with at least one radiation source located at a stand-off distance from the first detector;
receiving from a second detector in the detector set, a second radiation photon count associated with the second detector, wherein the second radiation photon count is associated with the at least one radiation source which is located at a stand-off distance from the second detector;
comparing the first radiation photon count to the second radiation photon count;
identifying, based on the comparing, that one of the first detector and the second detector has detected a larger number of radiation photons than the other; and
determining, based on the identifying, that the at least one radiation source is in a direction that is substantially identical to a direction in which the one of the first detector and the second detector that has detected the larger number of radiation photons is facing.

Abstract
A system and method determine a direction associated with gamma and/or neutron radiation emissions. A first radiation photon count associated with a first detector in a detector set is received from the first detector. The first radiation photon count is associated with at least one radiation source. A second radiation photon count associated with a second detector in the detector set is received from the second detector. The first radiation photon count is compared to the second radiation photon count. One of the first detector and the second detector is identified to have detected a larger number of radiation photons than the other. The at least one radiation source is determined to be substantially in a direction in which the one of the first detector and the second detector that has detected the larger number of radiation photons is facing.
