Global concern for the illicit transportation and trafficking of nuclear materials and other
radioactive sources is on the rise, with efficient and rapid security and non-proliferation …

The non-intrusive screening of shipping containers at national borders serves as a
prominent and vital component in deterring and detecting the illicit transportation of …

In order to detect special nuclear materials and other radioactive materials in Security and
Defense scenarios, normally, a combination of neutron and gamma-ray detection systems is …

Locating lost radioactive sources quickly, precisely, and safely is very important in
emergency responses of lost radioactive source accidents. This paper describes a source …

When hazardous sources threaten the environment, source term estimation is a crucial
concern. Robotics provides a secure solution to the issue but still encounters challenges in …

Radioactive source localization plays an important role in tracking radiation threats in
homeland security tasks. Its real-time application requires computationally efficient and …

Using a series of detector measurements taken at different locations to localize a source of
radiation is a well-studied problem. The source of radiation is sometimes constrained to a …

This paper addresses a detection problem where sparse measurements are utilized to
estimate the source parameters in a mixed multi-modal radiation field. As the limitation of …

We present a method for localizing an unknown source of radiation in an urban environment
using a distributed detector network. This method employs statistical parameter estimation …

Predictive estimation of radioactive sources using Bayesian theory is of great importance in
nuclear emergency response. To this aim, we put forward an unscented particle filtering …
