"Detecting Small Low Emission Radiating Sources,"
Poster presented at The 4th annual Domestic Nuclear Detection Office (DNDO) Academic Research Initiative (ARI) Grantees Conference, Alexandria, Virginia, April 26-28, 2011.
Illicit radiating sources in cargo containers, cars, or other
objects that cross the border can be well described as mall
point-like sources whose intrinsic radiance is often less,
sometimes much less, than the background radiation level.
Traditional detectors therefore have difficulties finding these
sources, but we can ask what characteristics detectors have to be
able to identify from such sources. We discuss how the
addition of some angular sensitivity-for example in the form of
Compton camera information-together with the assumption of small
sources can make detection of sources highly likely, even if the
background radiation is orders of magnitude stronger than the
radiation emitted by the source.
