• Virtual Imaging: versatile detection at low radiation dosage

    Virtual Imaging, a Canon U.S.A. Company, is offering its RadPRO SecurPASS, a full body security screening system that detects and recognizes a range of objects and materials in about eight seconds per person; it uses transmission imaging with an exceptionally low dose of X-rays to scan for dangerous or illegal substances such as liquid explosives, drugs, copper wires, plastic, etc.; its applications range from civil security, that is, airports, seaports, railways, bus stations, to border security, prison security, and high level security as necessitated by nuclear power plants, military premises, and embassies

  • Indian explosives detection technology comes to U.S.

    A south Carolina-based company signs a memorandum of understanding with India’s Defense Research and Development Organization (DRDO) to enhance the DRDO-developed Explosives Detection Kit (EDK) so it meets standards that will allowed it to be used by the U.S. military and homeland security

  • Insider threats in Afghanistan increase need for explosive detectors

    In Afghanistan suicide bombers are increasingly disguising themselves as friendly forces to successfully infiltrate secure allied bases and wreak havoc; April has been a deadly month for allied troops in Afghanistan with at least four attacks taking place where suicide bombers disguised themselves as police officers or members of the army; to protect against this threat, Thermal Matrix specializes in person-borne improvised explosive device (PBIED) detection devices; the firm has been working with the U.S military for the past several years to develop the Thermal Matrix ACT system which is capable of detecting suicide bombers from long distances; the system uses infrared imagery to analyze the heat signature of approaching individuals to determine if they are carrying any explosives

  • British company purchases American IED detection firm for $90M

    Last week the British defense firm Chemring finalized a deal to purchase Detection Systems, a subsidiary of General Dynamics, for $90 million; North Carolina based Detection Systems specializes in improvised explosive devices (IED) sensor systems; Detection Systems currently supplies the U.S. military with vehicle mounted IED detectors; the acquisition helps to enhance Chemring’s existing IED detection capabilities and provides growth opportunities for its chemical and biological detection programs; the purchase will not be finalized until the U.S. government reviews the proposal

  • Cooling pools or dry casks for nuclear waste: which is safer

    There are two ways to store nuclear waste: in pools of water, where the densely packed uranium rods are cooled by a constant flow of circulating water, or in dry casks — typically barrel-shaped steel-and-concrete structures that stand twenty feet high and sit outdoors — where the uranium loosely packed rods are cooled by passive air; there are 65,000 tons of nuclear waste in the United States, more than in any other nation, and this amount grows by about 2,200 tons each year; the Fukushima disaster demonstrated that dry casks were able to withstand the 11 March combination of earthquake and tsunami much better than cooling pools; the U.S. Nuclear Regulatory Commission must now decide whether cooling pools are safe enough to store nuclear waste, and even whether densely packing nuclear waste is safe

  • Chernobyl radiation did not damage abundance, diversity of aquatic life

    A new study of the lakes in and around Chernobyl’s fallout zone reveals that radiation from the nuclear accident appears to have had no long term effect on the abundance or diversity of aquatic animal life; no evidence was found that the abundance or diversity of the animal communities was influenced by direct contamination from the Chernobyl accident; indeed, the most contaminated lake, Glubokoye, 6.5 km north of the nuclear power plant, supported the most animal diversity of those lakes studied

  • Space technology of practical uses on Earth

    Terahertz technology developed for space missions to study the most distant objects in the universe is now finding a host of practical applications back on Earth; most clothing and packaging materials are transparent to Terahertz radiation, whereas skin, water, metal and a host of other interesting materials are not; this gives rise to some important day-to-day applications: detecting weapons concealed under clothing or inside parcels; distinguishing skin and breast cancer tissue; quality control of manufactures items and processes in factories

  • Trees as contamination detectors

    Determining the presence and concentration of contaminants has been an invasive, laborious process; now a Missouri University of Science and Technology team has developed a faster, more economical method of determining such contamination at miniscule levels; the Army has funded additional research for explosive residue detection

  • New material cleans water of radioactive contamination

    NC State researchers develops material to remove radioactive contaminants from drinking water; the material is a combination of forest byproducts and crustacean shells; the new material not only absorbs water, but can actually extract contaminates, such as radioactive iodide, from the water itself; this material, which forms a solid foam, has applications beyond radioactive materials

  • NRC inspects Nebraska reactor radiation exposure

    On 3 April, workers at the Cooper Nuclear Station, located near Brownville, Nebraska removed a long tube contaminated with highly radioactive material through the bottom of the reactor vessel, rather than through the top as is usually done, triggering radiation alarms; the NRC is investigating

  • DHS: U.S. unprepared for nuclear disaster

    Confidential DHS report says the United States is ill-prepared for a nuclear disaster — either an accident or a terrorist attack; just one example: if a major nuclear bomb were to hit Washington, D.C., there would be a need for about 61,000 beds in intensive care units; there are, however, only 118,000 intensive care beds in the entire United States and, on any given day, only 9,400 are free.

  • Army seeks long distance explosive detection scanners for people

    The U.S. Army is seeking to rapidly deploy long distance chemical detection devices that are capable of detecting explosives hidden on people; ideally, the devices will be able to sense the presence of explosives and chemicals on people standing, walking, or running from as far away as 100 yards; the Army wants to be able to field these capabilities within a year, so it is only considering mature technologies that are ready to be implemented; the request for proposals will close on 6 May

  • Russia to employ hi-tech bomb-sniffing dog

    In response to a series of terrorist attacks, Russia’s president Dmitry Medvedev has called on Russian military and security services to train more dogs as bomb sniffers; the dogs are trained not only in identifying explosives, but are also trained in carrying walkie-talkies so they can be given instructions from a distance, and to carry portable video cameras for in-building surveillance
