A form of tomography, the system enables quick 3D imaging of the source of neutron and gamma ray emissions from weapons-grade plutonium and other special nuclear materials, Cederwall said in a statement.
The so-called Neutron-Gamma Emission Tomography (NGET) system goes beyond the capabilities of existing radiation portal monitors by measuring the time and energy correlations between particles emitted in nuclear fission. It then uses machine learning algorithms to visualise where they are coming from. The system looks for coincidences of neutron and gamma ray emissions, which pinpoint their origin when mapped together in real-time.
”The technology has a very high sensitivity and can within a few seconds detect gram-amounts of plutonium depending on the application and the plutonium isotope composition,” Cederwall said. “It takes a little longer to get a really good picture so you can see exactly where the plutonium is. However, this can be done completely automatically.”
