• Pentagon: dogs better than technology at bomb detection

    The most sophisticated detectors the Pentagon came up with tend to locate only 50 percent of IEDs in Afghanistan and Iraq; when soldiers are accompanied by bomb-sniffing dogs, this number goes up to 80 percent; the Pentagon now spends less money on IED detection and more money on drones to find those planting IEDs, radio jammers to disrupt the frequencies used to detonate the bombs, and lots of aerial sensors to scan bomb-heavy areas

  • Drive-by X-ray vans raise privacy, health worries

    DHS, the U.S. military, and even local law enforcement agencies are buying and deploying mobile X-ray vans that can see into the interior of vehicles around them; the Z Backscatter Van (ZBV), manufactured by American Science and Engineering (AS&E), can be used to detect contraband such as car bombs, drugs, and people in hiding; the van looks like a standard delivery van, and it takes less than fifteen seconds to scan passing vehicles; it can be operated remotely from more than 1,500 feet and can be equipped with optional technology to identify radioactivity as well; the vans, which can also see through clothing and into some buildings, are raising privacy concerns as well as questions about health risks — and what might happen if the technology gets into the wrong hands

  • Bomb-sniffing dogs in Afghanistan, Iraq may not be up to the task

    The U.S. State Department uses nearly 200 bomb-sniffing dogs in Iraq and Afghanistan to protect U.S. diplomatic facilities; the department inspector general says that bomb-sniffing dogs in Afghanistan and Iraq are not being tested properly and may not be able effectively to detect explosives

  • Local resistance to bomb sniffing-dogs training facility

    As fear of domestic terrorism grows, so does the need for explosive-sniffing dogs; company with DHS detection credentials wants to convert a horse barn in New York into a commercial kennel for bomb-sniffing dogs, but the neighbors object

  • New way to sniff out shoe bombs

    Triacetone triperoxide (TATP) is a high-powered explosive that in recent years has been used in several bombing attempts. TATP is easy to prepare from readily available components and has been difficult to detect. It defies most standard methods of chemical sensing: It does not fluoresce, absorb ultraviolet light, or readily ionize; University of Illinois researchers offers a solution that overcomes these problems

  • End to limits on carrying liquids on board in sight

    New bottled liquid scanners unveiled; researchers at the Los Alamos National Laboratory developed a magnetic resonance device to read liquids’ molecular makeup, even when the substances are in metal containers; the device is so sensitive it can tell the difference between red and white wine, and between different types of soda; satisfactory test result may spell the end of limitations on carrying liquids on board

  • New nuclear detection method does not use helium

    Current nuclear detection technology uses helium 3, which was a by-product of the U.S. earlier nuclear weapons programs and which is in increasingly short supply; Dynasil’s new “dual mode” detectors are designed to work without helium 3 and can replace two separate nuclear detector systems for gamma radiation and for the neutrons from nuclear materials

  • Italian airport security drop body scanners

    After a six-month test, Italy is giving up full-body scanners for security checks in airports; officials said it takes longer to check a person by scanner — about thirty seconds — than by hand, and privacy measures reduced the scanners’ effectiveness

  • New detector tests for illegal drugs, superbugs in minutes

    A new method of detecting illegal drugs and super bugs will be used in a U.K. government-backed handheld device that analyzes saliva; the testing takes minutes and costs as little as £1.50 per test; it works by measuring the electric charge generated when the substances in the saliva react with an electrode coated with antibodies

  • New TNT detector 1,000 more sensitive than sniffer dogs

    Israeli researchers develop an explosives detector that can detect extremely small traces of commonly used explosives in liquid or air in a few seconds; the device is a thousand times more sensitive than the current gold standard in explosives detection: the sniffer dog

  • DHS gives New York $18 million for radiation detection system

    DHS will hand New York $18.5 million today to keep the city’s prototype dirty-bomb detection system running; the nuclear detection operation is run out of an operations center in the city, featuring more than 4,500 pieces of radiation detection equipment, many equipped with GPS locators

  • DHS announces $98 million for advanced X-ray technologies

    Next-generation advanced technology (AT) X-ray systems screen carry-on baggage for explosives or prohibited items at checkpoints; currently, TSA employs more than 940 AT X-ray units at airports nationwide; $98 million will fund the deployment of additional units

  • GAO: $4 billion border radiation detectors program a bust

    The Government Accountability Office (GAO) reported Wednesday that the $4 billion program to install radiation detectors at U.S. border crossings yielded few tangible results; the detection machines were too big for border inspection lanes, and the software for the Cargo Advanced Automated Radiography Systems also was not up to the task; DHS: “We are mindful of getting something delivered that has a credible basis for the implementation plan that follows”

  • Insect-size air vehicles to explore, monitor hazardous environments

    High-performance micro air vehicles (MAVs) are on track to evolve into robotic, insect-scale devices for monitoring and exploration of hazardous environments, such as collapsed structures, caves and chemical spills

  • 1st Detect in $735,000 contract for chemical detection in the field

    Phase II SBIR contract from the Joint Science & Technology Office for Chemical and Biological Defense will allow the company to design and develop a novel sample inlet system intended to improve the sensitivity of mass spectrometers used for chemical detection in the field
