A. This class of materials can be compared to props, designed to trigger a threat assessment at the screening point. Some simulants may actually look like bombs, but there's a lot more to it.

A. Trick question. X-rays wern't invented by anybody. They are a naturally occuring light wave discovered on November 8, 1895 by William Roentgen

A. Our High-energy X-ray NESTT can be formed into any shape... like this frog. It's malleable and can simulate Semtex, C4 and other military explosives.

A. Sure, X-rays see metal like the nails in the shoe heel. But baggage screening equipment also highlights materials and densities that match explosives. Our simulants duplicate these densities. A simple visual inspection might not reveal the danger but the material density does.
