• Air data can be used to reconstruct radiological releases

    New research demonstrates that experts can use data from air sampling technology to not only detect radiological releases, but to accurately quantify the magnitude and source of the release. This has applications for nuclear plant safety, as well as national security and nuclear nonproliferation monitoring.

  • U.S. testing radiation therapy developed in Israel

    The United States will likely begin to stock anti-radiation therapy from Pluristem Therapeutics Inc., an Israeli biotech company. The company says that the therapy can also cure nearly all people exposed to the radiation effects of nuclear weapons, “dirty” bombs, or nuclear power plants.

  • Predicting clay swelling for better nuclear waste disposal

    Bentonite clay is planned to be used as a key barrier in the deep geological disposal of high-level nuclear waste. To ensure the safety of disposal, it is crucial to understand and predict the swelling behavior of bentonite clay. The swelling property, however, is regulated by multiple structural and environmental factors. A new model simulates the atomic-level interactions among the components of clay-water system, reproducing the swelling trends and swelling pressures measured by experiments with good accuracy.

  • ISIS may get its hands on “highly dangerous” nuclear material stolen in Iraq

    Iraqi security agencies are searching for “highly dangerous” radioactive material stolen last year.  Experts are worried that the material could fall into the hands of ISIS. The material – Ir-192 — is designated a Category 2 radioactive by the IAEA, and it could be used to build a “dirty bomb,” which combines nuclear material with conventional explosives to contaminate an area with radiation.

  • Specialized ORNL team uses nuclear forensics to solve mysteries, safeguard materials

    From the Manhattan Project in the 1940s to the High Flux Isotope Reactor’s 50th anniversary and its selection as an American Nuclear Society Nuclear Historic Landmark, the Department of Energy’s Oak Ridge National Laboratory (ORNL) has been the preeminent destination for nuclear R&D. A group of nuclear detectives at ORNL) takes on tough challenges, from detecting illicit uranium using isotopic “fingerprints” to investigating presidential assassination conspiracies.

  • Symetrica inaugurates Radioactive Threat Verification Solutions Hub

    Southampton, U.K.-based Symetrica has inaugurated the company’s new Radioactive Threat Verification (RTV) Solutions Hub. The company says that the new facility will improve the company’s ability to support the global security community – including the U.K.’s Home Office and Border Force, the U.S. Department of Homeland Security, and other border protection agencies.

  • New X-ray method could detect nuclear materials

    Inspectors need tools to help find nuclear materials hidden behind thick shielding or smuggled inside any of the 100 million-plus cargo containers shipped around the world each year. Uranium is perhaps the easiest nuclear material to obtain and hide. Physicists have demonstrated that their unconventional laser-based X-ray machine could provide a new defense against nuclear terrorism. The scientists used the laser-driven X-ray source to produce an image of a uranium disk no bigger than a stack of three nickels and hidden between 3-inch steel panels.

  • Demonstrating technologies for disaster response

    Radiological incidents such as Chernobyl and Fukushima illustrate the need for effective coordination of federal, state, and local agencies in response efforts. Earlier this year, the Department of Homeland Security (DHS) Science and Technology Directorate’s (S&T) National Urban Security Technology Laboratory (NUSTL) and the Environmental Protection Agency (EPA) demonstrated new technology developments at the Columbus, Ohio, Battelle Memorial Institute facility that will enable more effective radiological decontamination.

  • Inspired by cats’ eyes, new camera can look inside nuclear reactors

    Currently 11 percent of electricity worldwide is generated by nuclear reactors. There are 435 reactors in operation with another 71 under construction. Engineers, drawing inspiration from the eyes of cats, have created a new camera that can see radiation coming from nuclear reactors — boosting safety, efficiency, and helping during nuclear disaster emergencies.

  • Search in Illinois, Indiana for missing canister holding radioactive materials

    Teams from the Illinois Emergency Management Agency (IEMA) are continuing their search in Illinois and neighboring Indiana for a missing steel canister containing radioactive material. The locked steel canister was last believed to be in a custom oil well logging truck. The nuclear material was used by an Illinois company specializing in surveying oil wells.

  • $100 million NIAID contract to SRI International to develop radiation exposure treatment

    SRI International has been awarded a resource contract of up to $100 million over five years by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, for the development of products to mitigate or treat acute or delayed effects of radiation exposure.

  • FBI helps foil several plots to sell nuclear material in Moldova’s black market

    Over the past five years, four attempts by Russian gangs in Moldova to sell nuclear material have been thwarted by the FBI and Moldovan authorities. The most recent case was in February when a smuggler, who specifically sought a buyer from Islamic State, offered undercover agents a large amount of radioactive caesium. The would-be smuggler wanted €2.5 million for enough radioactive material to contaminate several city streets.

  • Animals have returned to Chernobyl

    In 1986, after a fire and explosion at the Chernobyl Nuclear Power Plant released radioactive particles into the air, thousands of people left the area, never to return. Now, researchers have found that the Chernobyl site looks less like a disaster zone and more like a nature preserve, teeming with elk, roe deer, red deer, wild boar, and wolves. The findings are a reminder of the resilience of wildlife.

  • Upholding disarmament agreements with engineering

    Arms control agreements face a problem: how to ensure that countries with nuclear weapons abide by disarmament agreements. The linchpin of these agreements is being able to verify that the signers are following the rules — but the trick is for both sides, or a third party, to be able to police weapons in a way that doesn’t give out too much information about them, for example, how these weapons were built. An MIT project, called Zero Knowledge Warhead Verification, tackles this problem with a beam of light, a scrambler, and a detector.

  • Mighty Saber demonstrates post-nuclear detonation technical forensics capabilities

    In late 2013, a team of more than fifty scientists from across the U.S. laboratory and industrial complex began preparing for Mighty Saber with the goal of demonstrating and evaluating post-detonation technical nuclear forensics capabilities following a simulated detonation of a nuclear device in an urban environment. Mighty Saber, which ran from 27 July to 21 August 2015, successfully met each of its objectives, including demonstrating U.S. government post- detonation nuclear forensics processes; the value of prompt diagnostics data provided by the Discreet Oculus ground-based sensor network; and how prompt diagnostics complements radiochemistry in providing a robust post-detonation nuclear forensics capability.
