The ability to map and estimate the activity of radiological source distributions in unknown
three-dimensional environments has applications in the prevention and response to …

Networked detector systems can be deployed in urban environments to aid in the detection
and localization of radiological and/or nuclear material. However, effectively responding to …

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 …

The Polaris-LAMP multi-modal 3-D gamma-ray imager is a radiation mapping and imaging
platform which uses a commercial off-the-shelf (COTS) detector integrated with a contextual …

A particle filter algorithm is presented to estimate the position, strength, and cardinality of an
unknown number of radioactive point sources in an obstacle-rich environment using count …

Airborne gamma ray spectrum detection technology is an effective means to measure the
concentration and spatial distribution of natural radionuclides in environmental media such …

We discuss the localization of radiation sources whose number and other relevant
parameters are not known in advance. The data collection is ensured by an autonomous …

With increasing demand in the nuclear technology field for locating isolated radioactive
sources, numerous studies have focused on the array detector. Given the concerns over the …

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 …
