Abstract:
1. A radiation detection system comprising: a receiver configured to continuously receive radiation emission data from at least some of a sufficient density of dispersed detectors capable of communicating geo-positions and photon emission counts over a wireless network, wherein the radiation emission data includes gamma intensities, time stamps, and geo-positions affiliated therewith reported in real time; a processor coupled with the receiver and configured to build digital image data of the received radiation emission data for a geographic area by treating emission data from each dispersed detector as an image pixel in a low-light image; a database coupled with the processor, to store the digital image data; wherein the processor is configured to continuously execute a plurality of statistical computational analyses on the digital image data to separate detected radiation signals from random, undesired signal noise, wherein the plurality of statistical computational analyses comprise match-filter, other convolution techniques, or a combination thereof; and an interface configured to report to a user when the plurality of statistical computational analyses result in detection of a radiation signal and to report a location of one or more of the dispersed detectors that contribute to the detection.
