Abstract

The work proposed will study, develop, and implement efficient gradient detection methods and
algorithms for localizing radiation sources using a single non‐directional detector. Exploitation of
gradients introduced by source‐to‐detector distance – through natural or deliberate motion – and those
introduced by body‐shielding will allow for localization and tracking of sources in a pedestrian‐based
search scenario. Available technologies for position determination (e.g. MEMs‐based INUs) will be
evaluated and integrated into existing spectroscopic radiation detection platforms, and existing
advanced Bayesian inference algorithms will be updated to utilize new relative position data. Both the
advanced algorithms and the spectroscopic radiation detectors were previously developed under the
IRSS ATD program. Their use for this proposed work will significantly reduce both cost and risk.
