HiEnergy Technologies, Inc. (OTC Bulletin Board: HIET), the homeland security industry leader in neutron-based diagnostic technology, announced that it will present its novel robotic vehicle Atometer(TM) detector of Improvised Explosive Devices (IEDs) today at the Unmanned Ground and Sea Systems Conference being held in Washington D.C. from April 5 - 7, 2006.


The conference includes more than 40 distinguished experts in the field of unmanned warfare and threat defeat from the Office of the Secretary of Defense, U.S. Army, Navy, Air Force, NASA, Boeing, Lockheed Martin, and others, and is sponsored by The American Institute of Engineers, National Military Intelligence Association and the Naval Aviation Foundation.


Dr. Alex Vaucher, HiEnergy Technologies' head of R&D, is to present HiEnergy's STARRAY(TM) robot-borne Atometer(TM) explosive detector and discuss the continuing research and development efforts by HiEnergy's scientific team in the detection and defeat of IEDs, landmines and unexploded ordnance.


IEDs and car bombs in particular have become the single most destructive threat to our deployed military personnel. Accordingly, the U.S. Army has continued research and development with the goal of deploying new advanced detection and defeat techniques, including our stoichiometric technology, and protecting the lives of brave Servicemen and innocent civilians from these deadly threats.


Over the last year, HiEnergy Technologies has been advancing the development and commercialization of its STARRAY(TM) robotic vehicle system in order to help defeat these threats. In October 2005, HiEnergy Technologies announced that the U.S. Army selected its white paper on its robot-borne detector of IEDs and landmines for submission of a full proposal, and in December 2005, HiEnergy Technologies announced the appropriation of US$1 million for further development of stoichiometric explosive detection systems with the U.S. Army under Program Element 0602712A.


The STARRAY(TM) is HiEnergy Technologies' latest robot-borne Atometer(TM) explosives detection system. The STARRAY(TM) can cover rough terrain, climb stairs, clear obstacles and cross ditches in diverse weather and heat conditions and is capable of non-invasively determining within minutes the presence of landmines, concealed explosives or unexploded ordnances in a specific area, and the type of munitions or explosives discovered. In September and October of 2005, the U.S. Army conducted extensive tests of the STARRAY(TM) prototype.


ABOUT HIENERGY TECHNOLOGIES, INC. (http://www.hienergyinc.com)


HiEnergy Technologies, Inc. is the creator of the world's first "stoichiometric" diagnostic devices that can effectively decipher chemical composition of unknown substances through metal or other barriers, almost instantly and without human intervention. HiEnergy's products incorporate a proprietary interrogation process which activates a selected target with neutrons causing the contents to emit back gamma rays that contain unique signatures from which the chemical formulas are derived. HiEnergy believes its Atometry(TM) technology compares with other detection technologies like color photography compares with black-and-white photography.


HiEnergy is focused on the commercialization and sale of the world's first "stoichiometric" explosive diagnostic devices, including the SIEGMA(TM) 3E3 and the CarBomb Finder(TM) 3C4, a vehicle-borne system, for the detection and identification of car bombs. The Company is marketing its devices to governmental and private entities and is negotiating licenses for distribution of its devices with various industry partners. The Company also continues to focus on the research and development of additional applications of its technologies and their further exploitation, both internally and through collaboration with third parties.
