Efficient and Robust Localization of Multiple Radiation Sources in Complex Environments

Free registration required

Executive Summary

There has been increasing interest in the detection and localization of radiation sources as part of the defense strategy against Radiological Dispersal Devices (RDD) commonly known as dirty bombs. In particular, the higher concentration of people in urban areas increases the susceptibility to coordinated dirty bomb attacks. Harmful radioactive substances unleashed in such an attack could cause widespread health and environmental damage, since such substances would be hard to clean up and would cause adverse effects from long term exposure. The ability to quickly detect and localize illicit radiation sources is crucial. Such swift actions enable authorities to find and remove RDDs during transport or storage. Moreover, attackers may launch a coordinated attack involving multiple RDDs installed at different places.
