New Demron-W Technology Awarded NFPA Class 2 Certification, Launched as World’s Only Protective Ensemble for All Chemical, Biological, Radiological and Nuclear Incidents

July 22,2008


MIAMI – Ronald DeMeo, MD, MBA, president and chief executive officer with Radiation Shield Technologies (RST), today announced the new Demron-W technology has been awarded NFPA Class 2 Certification for Protective Ensembles for First Responders to CBRN Terrorism Incidents. RST enhanced its original Demron nuclear-radiation protection material to enable it to block all biological- and chemical-warfare agents, making the new Demron-W the world’s first and only protective ensemble for all types of chemical, biological, radiological and nuclear incidents.
Demron and the new Demron-W, RST’s core technologies, consist of an advanced radiopaque nano-polymeric compound fused between layers of fabric and manufactured into several lightweight, nuclear-radiation blocking garments, including full-body suits, vests, blankets and medical X-ray vests and aprons. The company will continue to sell both Demron and Demron-W product lines.
 “Our military and first-responders traditionally have had to choose what protective suit to wear according to the specific threat they faced, and our new Demron-W suits eliminate the guesswork by providing complete protection from all types of chemical, biological, radiological and nuclear hazards,” said DeMeo, the surgeon who developed the Demron technology. “Radiation Shield Technologies remains committed to developing advanced personal-protection solutions while promoting awareness, education and scientific research to advance the field.”
Demron-W fabric passed all tests in accordance with the Class 2 requirements of NFPA 1994-2007 Standard on Protective Ensembles for First Responders to CBRN Terrorism Incidents. Underwriters Laboratories (UL) awarded the certification. The official certification may be viewed on UL’s Web site at To receive the NFPA Class 2 certification, protective materials must pass tests for permeation resistance and offer protection against several chemical warfare agents, including mustard gas, soman, and liquid and gaseous industrious chemicals. In other studies and tests, Demron has been proved to block gamma rays, X-rays and nuclear emissions by the Lawrence Livermore National Laboratory, part of the National Nuclear Security Administration within the U.S. Department of Energy, as well as the Georgia Institute of Technology and the Columbia University College of Physicians and Surgeons.
Demron technologies provide more protection than the current NBC suits, which offer no shielding against ionizing radioactive sources, such as dirty bombs and nuclear spills. Demron is the only personal-protection system that provides complete alpha, beta and low-energy gamma protection along with total nuclear-radiation protection. Demron technologies are deployed worldwide by NATO, NASA, the National Guard, US Navy, UAE and the governments of South Korea, China, Saudi Arabia and Australia, among others. Scientists have selected it for space suits for future Mars and other space travel.
Demron, made of liquid metal, is designed to feel cool and flexible and enable users to perform a full range of duties. It is a lead-free, toxin-free, and PVC-free material that allows heat dissipation and resists chemical penetration and cracks.
