MIAMI, May 7 (UPI) -- The Australian patent office says it has granted Radiation Shield Technologies a new patent for the company's Demron radiation-protection material.

Demron is a lightweight liquid metal compound that feels like fabric made from nanotechnology that when worn as a suit provides security and military authorities some protection from nuclear radiation, chemical and biological threats. Company officials say IP Australia has granted a new Australian patent for Demron.

Demron, which has other Australian, United States, Singaporean and Russian patents, has been deployed by NATO, NASA, the U.S. National Guard and U.S. Navy among other agencies around the world.

"The global demand and deployment of Demron exceeds our expectations and reaffirms its leadership as the only nuclear radiation-blocking material that also provides anti-chemical and biological protection," Ronald DeMeo, Radiation Shield Technologies president and chief executive officer, said in a statement. "Demron's patents will help us expand its market potential, and we will continue to secure patents worldwide."
