• Speedier Security Screening in the Palm of the Hand

    Though pat downs are currently an essential element of keeping travelers safe at the airport, it slows the screening process for people waiting in line and can be an uncomfortable experience for the passenger being screened. Reducing the need for pat downs may soon be easier.

  • Iran Triples Production of Enriched Uranium

    Iran has tripled its production of uranium enriched to 60 percent, after slowing down of production earlier this year, the International Atomic Energy Agency (IAEA) reported on Tuesday. Iran, free of the restrictions it accepted as part of the 2015 deal, is now producing about 9 kg a month of uranium enriched to 60 percent.

  • Leveraging Artificial Intelligence in Explosives, Narcotic Detection

    DHS S&T is applying emerging technologies in the development of artificial intelligence / machine learning technologies – and searching for ways to use these technologies to identify dangerous compounds, like those found in explosives and narcotics.

  • A Self-Service Screening Option Coming to the Airport Near You

    Self-service screening is coming to airport checkpoints, thanks to the Science and Technology Directorate’s Screening at Speed Program. A pilot of a new self-service screening system is scheduled to begin in January at Harry Reid International Airport in Las Vegas, Nevada.

  • Bioengineered Potato Plant Detects Gamma Radiation

    A researcher in the University of Tennessee Herbert College of Agriculture has developed a potato plant that can detect gamma radiation, providing reliable indications of harmful radiation levels without complex monitoring technologies. The natural radiation sensor is affordable, too.

  • Preparing U.S., Partners for Radiological Response

    After the September 11th attacks, security professionals worried that terrorists might detonate a “dirty bomb” – an explosive device enhanced with radiological source materials. Responders for this type of event had to be trained.

  • Los Alamos National Lab Safely Shipping Radiological and Hazardous Waste Off-Site

    A substantial amount of Los Alamos National Lab’s radiological and hazardous waste from years past was permanently disposed of at off-site facilities — a move in step with the Lab’s goal to mitigate hazards to workers, the community, and the environment while carrying out its national security mission.

  • Chlorine Is a Highly Useful Chemical That’s Also Extremely Dangerous − Here’s What to Know About Staying Safe Around It

    Chlorine is extremely toxic, and because it’s ubiquitous in many industries across the U.S., it often is released in chemical accidents and spills. As with other household chemicals, it is very important to understand its risks, read labels before using it, store it in its original container in a secure place and dispose of it safely.

  • Detecting Nuclear Materials Using Light

    Sandia materials scientist developed the state of the art technology known as Organic Glass Scintillators for radiation detection. Organic Glass Scintillators emit light in the presence of radiation.

  • Striving for a More Secure World

    PNNL experts work with international partners to tackle cross-border biological and chemical threats. PNNL’s border security focus can be traced to the breakup of the Soviet Union in the early 1990s. U.S. policy makers became concerned about the security of nuclear material in the newly independent states of the former U.S.S.R.

  • New Zealand: Firm Found Guilty Over Volcano Disaster

    The court said Whakaari Management failed to sufficiently “assess risk” to visitors or provide them with protective gear, leading to the death of 22 people.

  • Securing Ports of Entry, One Scan (or Thousands) at a Time

    Every year, millions of cargo containers make their way to U.S. ports of entry via maritime, roadways, and railways. According to U.S. Customs and Border Protection (CBP), more than 100,000 commercial cargo trucks cross U.S. POEs daily. To combat the threat of human and drug trafficking, it is imperative that their methods for cargo screening and physical examination are as thorough as they are efficient.

  • Happy 60th Birthday to Vela, Watchman for Nuclear Detonations

    Sixty years ago last week, on Oct. 16, 1963, the United States launched a pair of satellites whose primary purpose was to determine the feasibility of using satellites to detect nuclear detonations in outer space. The satellites were part of the Vela program, initiated in 1959 to provide a nuclear detonation detection capability to verify compliance with nuclear treaties. On Sept. 27, 1984, the last of the Vela satellites were turned off.

  • Testing Seafloor Fiber Optic Cable as an Earthquake Early Warning System

    One of the biggest challenges for earthquake early warning systems (EEW) is the lack of seismic stations located offshore of heavily populated coastlines, where some of the world’s most seismically active regions are located. Researchers show how unused telecommunications fiber optic cable can be transformed for offshore EEW.
