A Pitstop On The Information Super Highway


December 1st, 2007 Posted in Science and Technology

Taking off you shoes at airport security checkpoints could be a thing of the past if new scanners using T-rays are developed and put into place.? According to researchers at the U.S. Department of Energy’s Argonne National Laboratory T-rays which are a form of electromagnetic radiation and believed to be harmless could make that possible.

The equipment to produce T-rays has been large and bulky but the US researchers have been working with researchers from Turkey and Japan and have found a simple was to generate T-rays using special high temperature superconducting crystals in a very compact device.

T-rays or terahertz radiation are part of the eletromagnetic spectrum between mircowaves and infrared radiation.? T-rays do not have enough energy to alter cells which leads to radiation sickness or cancer like conventional X-rays.? They don’t have the penetrating power to see through metals or water but they can penetrate many common materials such as paper, cardboard, leather and fabrics.? They are also sensitive to various chemical characteristics used in weapons and potential harmful chemical formulas something that X-rays cannot do.
