Radiation Monitoring, Screening and Characterization

Arktis' platform technology offers a tool with unique capabilities for the detection of fast neutrons and gamma radiation, with novel capabilities in the following fields:

Radiation Portal Monitoring (RPM)

Radiation portal monitors (RPM) are detection devices that provide  passive, non-intrusive means to scan trucks and other conveyances for the presence of nuclear and radiological materials (nuclear weapons, dirty bombs, components). RPMs are frequently deployed for cargo scanning in the homeland security domain. 

Size: RPMs are deployed for the purposes including personnel screening (mid-scale) up to truck or railway car screening (large scale).

Goal: Reliable detection of shielded radiological threats with infrequent false/nuisance (currently up to 4% nuisance alarm rate).

Arktis’ fast neutron detection technology offers increased potential to detect weak and heavily shielded nuclear materials (U, Pu) that elude detection by conventional means. The technology delivers more information on the type of radiation detected than currently deployed detectors, allowing a significant reduction in nuisance alarms.

Markets: Border security, transportation security, non-proliferation, recycling industry

 

Nuclear Materials Assay

Goal: Obtain knowledge about the composition and activity of nuclear fuel at various stages of its life cycle, for example by monitoring the fissile content.

Markets: Nuclear power industry, non-proliferation, nuclear safeguards

Health Physics

Health physics deals with reliably monitoring the radiation dose in a given environment to which workers are exposed.

Example: Tissue damage caused by neutron radiation is highly energy dependent: Fast neutrons are several times more damaging than thermal neutrons. Nevertheless, conventional area monitors only assess neutron dose by neutron counting.

Arktis fast neutron detection technology allows measuring fast neutrons independently from thermal neutrons, and thereby more accurately monitoring the exposure experienced by workers. 

Markets: Nuclear industry, hospitals, space, research

Active Interrogation

Active Interrogation (AI) techniques use external radiation sources to stimulate a unique radiation signature from fissionable material.  

Markets: Border security, transportation security, non-proliferation, recycling industry, oil & gas, nuclear power industry, non-proliferation, nuclear safeguards
