New Liquid Screening Technology Tested for Airports

by : Jaco

In conjunction with US Homeland Security, a new liquid sceening technology is now being developed and tested by scientists within the US government. The new technology is said to be able to spot liquid explosives contained within luggage, and if approved and implemented, the new technology could do away with current handluggage restrictions.

The technology is based on MRI, (Brain-scanning Magnetic Resonance Imaging), and seems to have been quite successful so far. To establish the presence of liquid chemicals the scanner uses its' magnetic signatures to determine if a liquid can be deemed safe, or flagged as potentially dangerous. Once detected, the device uses one of three methods to display its' assessment of the scanned liquid.

A green dot is safe, yellow is unidentifiable, and red obviously indicates a potentially dangerous liquid. Using these methods, it is said the new technology will in essence be able to differentiate between a sports drink and a potentially dangerous liquid, and initial reports indicate that testing is scheduled for summer 2008 at Sunport Airport in Albuquerque.

Magnetic resonance imaging (MRI) - also referred to as magnetic resonance tomography uses a non-invasive method to render images of the inside of a selected object, and has up to now primarily been used in selected fields, such as the medical field, to "see" inside the human body.
