STAND OFF CBRN DETECTION TECHNOLOGY ON SHOW
Published – DECEMBER 2019 – JANUARY 2020 | WWW.AUSTRALIANDEFENCE.COM.AU
DISCOVERY™ provides 3D visualizations of the contents of cargo volumes, allowing the operator to explore and inspect the volume in three axes all from a stand-off range. This capability allows them to make informed decisions on the presence of threats, contraband and other smuggled items, using information that is simply beyond the capability of existing x-ray systems. Decision Sciences, a US based company, is working hand in hand with Australian SME J3Seven, to bring awareness of this technology into the Australian marketplace.
Originally invented at the Los Alamos National Laboratory, Decision Sciences has commercialized the technology providing radiation-free, fast, effective interrogation of cargo. Internal experts, including an ex-ABF non-intrusive inspection specialist, have significantly advanced the operational effectiveness of DISCOVERY™ through the development of sophisticated data interpretation techniques.
With no active source, DISCOVERY™ uses naturally occur-ring cosmic-ray generated muons and electrons, which are constantly raining down on the surface of the Earth, to per-form measurements of the contents of the cargo volume. Cosmic ray tomography is a technology that uses naturally occurring muons and electrons to generate 3D images. Cosmic rays shatter in the Earth’s atmosphere to produce a harmless flux of muons and electrons that continuously rain onto Earth. As the cosmic rays penetrate materials, their trajectory is changed based on the density and atomic number of the contents they interact with.
The technology utilized for performing these measurements has advanced 100-fold over the last few years. The passive nature of the system also means that other inspection activities can be performed uninterrupted inside the system without any need for exclusion zones. Checkpoint activities such as document control, K9, and physical inspection can all take place concurrently with the DISCOVERY™ inspection.
The system has virtually no moving parts and can be done in a fraction of the time compared to traditional scanning technologies. The technology has been trailed in the US, with the user feedback extremely positive thus far.
