Radiation mapping has attracted widespread research attention and increased public
concerns on environmental monitoring. Regarding materials and their configurations …

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 …

A prototype system based on a combination of 4 sensitive gamma imaging and
simultaneous localization and mapping (SLAM) was developed to find unknown radiation …

In this second part of a multipaper series, we present results from outdoor aerial
measurements of surrogate distributed gamma-ray sources. We detail the design …

An advanced spatial-unfolding technique capable of reconstructing the activity distribution
within an exclusion zone from Compton gamma imager measurements taken outside of it is …

A handheld system developed to digitize a contextual understanding of the scene at a
chemical, biological, radiological, nuclear and/or explosives (CBRNE) events is described …

The ability to formulate maps of minimum detectable activities (MDAs) that describe the
sensitivity of an ad hoc measurement that used one or more freely moving radiation detector …

The ability to localize and image radiation sources has found use in various applications for
nuclear nonproliferation practices, specifically in treaty verification, nuclear safeguards, and …

The imperative need for real-time systems to monitor radioactive materials cannot be
overstated, as they play a pivotal role in mitigating accidents involving radioactive materials …

Recent advances in machine learning (ML) based object recognition have enabled robotic
systems to autonomously navigate to and investigate sources of radiation such as nuclear …
