• Cold War nuclear legacy challenges science, society

    Fifty years of U.S. nuclear weapons production, and government-sponsored nuclear energy research and production, generated contaminated soil and groundwater covering two million acres in thirty-five states; for most of that period, the U.S. government did not have environmental structures, technologies, or infrastructure to deal with the problem

  • Pentagon expends cyber networks security project

    The Pentagon plans to extend a cyber defense pilot program intended to help protect U.S. defense contractors from cyberattacks to more private companies, subcontractors, and industries such as power plants

  • Study finds traces Japanese radiation in U.S. rain and food

    A recently published government study found that following the nuclear accident at the Fukushima Daiichi power plant in Japan, elevated levels of radiation were detected in U.S. rain water as well as vegetables and milk

  • Two radiation generators help protect U.S.

    One aspect of a nuclear explosion— the electro-magnetic pulse, or EMP — was much discussed during the cold war: scientists argued that exploding a nuclear bomb in the skies high above the United States would create an EMP which would disrupt electronic equipment and paralyze the nation; two remarkable pulsed-power machines used to test the U.S. defenses against atomic weapons have surpassed milestones at Sandia National Laboratories

  • New materials hold promise for better detection of nuclear weapons

    Researchers have developed new materials that can detect hard radiation, a very difficult thing to do; the method could lead to a hand-held device for detecting nuclear weapons and materials, such as a “nuclear bomb in a suitcase” scenario

  • Detecting contraband radioactive material

    Researchers are building a highly sensitive instrument that will detect illicit radioactive materials with pinpoint accuracy from a safe distance; such materials, located in shipping ports, train stations, truck stops, or warehouses, potentially could be used to make dirty bombs or associated with a nuclear device itself

  • Innovative plastic slashes cost of radiation detectors

    Japan’s Teijin Chemicals announced it will begin supplying scintirex, an innovative low-cost radiation-fluorescent plastic, in late September; scintirex will be used in scintillators — the material at the core of radioactive radiation detectors; the use of the new plastic will slash the production cost of scintillators to one tenth or less of current levels

  • Microbes clean up nuclear waste -- and generate electricity

    Researchers have discovered how microbes generate electricity while cleaning up nuclear waste and other toxic metals; the microbes effectively immobilize the radioactive material and prevent it from leaching into groundwater; the discovery could benefit sites changed forever by nuclear contamination

  • Teams dispatched to inspect Vermont nuclear plant following Irene

    Following the torrential rains from Hurricane Irene on Sunday, federal officials have dispatched inspection teams to examine the aging Vermont Yankee nuclear plant to ensure that the plant has not been compromised; the plant has the same design as the Fukushima Daiichi plant in Japan which suffered a partial meltdown following the 11 March earthquake and tsunami

  • Radiation detection market to see accelerated growth

    The radiation detection industry will see accelerated growth as a result of ongoing homeland security concerns to greater concerns about safety in the nuclear power industry; the growth will involve both increases in the volume of materials required, and in the types of materials being sought

  • Radiation fears cripple Japanese food exports

    Japanese agricultural exports have yet to recover from the 11 March earthquake and tsunami due largely to fears of radioactive contamination; to combat these fears, local governments have done all they can to assure consumers that their products are safe; consumers remain wary despite these reassurances, and as a result the Japanese agricultural sector is struggling

  • First quantitative measurements of Fukushima leakage

    Atmospheric chemists report the first quantitative measurement of the amount of radiation leaked from the damaged nuclear reactor in Fukushima; the researchers calculated that 400 billion neutrons were released per square meter surface of the cooling pools, between 13 March, when the seawater pumping operation began, and 20 March 2011

  • Cheap radiation detector made of PET resin developed

    Researchers develop a revolutionary radiation-sensitive plastic with a performance superior to plastic scintillators used for measuring radiation; the discovery will enable a major reduction in production costs — a step toward an inexpensive radiation detector available to everyone

  • Dallas launches regional nuke detectors

    The Dallas police will soon be participating in a regional radiological nuclear detection program that will help law enforcement officials detect any anomalies and help protect against any nuclear or radiological attacks

  • Underwater nuke detecting drone

    Unmanned underwater vehicles (UUV) could soon be prowling the nation’s coastline to detect radiological and nuclear threats; the underwater drones, developed by New Jersey based Princeton Security Technologies, Inc., are equipped with radiological isotope identification hardware to monitor any changes below the water
