Computer vision-based neural networks for radioisotope identification in urban environments
Masen Bachleda, Peter Lalor, Alea Minar +1
Algorithm development for radioisotope identification in mobile urban search scenarios face significant challenges from non-uniform backgrounds, momentary source encounters, and se…
Atomic number estimation of dual energy cargo radiographs: initial experimental results using a semiempirical transparency model
Peter Lalor, Areg Danagoulian
To combat the risk of nuclear smuggling, radiography systems are deployed at ports to scan cargo containers for concealed illicit materials. Dual energy radiography systems enable…
Atomic number estimation of dual energy cargo radiographs using a semiempirical transparency model
Peter Lalor, Areg Danagoulian
Dual energy cargo inspection systems are sensitive to both the area density and the atomic number of an imaged container due to the dependence of photon attenuation. The abilit…
Fundamental limitations of dual energy X-ray scanners for cargo content atomic number discrimination
Peter Lalor, Areg Danagoulian
To combat the risk of nuclear smuggling, radiography systems are deployed at ports to scan cargo containers for concealed illicit materials. Dual energy radiography systems enable…
