Theory aids analysis of nuclear materials

Aug. 22, 2018- 
Nuclear emergency teams, safeguards specialists and others may one day benefit from an expanded nuclear fission chain theory and detectors developed by a team of Lawrence Livermore Nationla Laboratory (LLNL) physicists.          The Livermore scientists have bolstered their theory for understanding nuclear fission chains --  a cascade of atomic nuclei splitting, each initiated by a neutron...

LLNL supports NYC subway biodefense test

June 9, 2016- 
Lawrence Livermore National Lab (LLNL) researchers took to the New York City subway system May 9-13 to help study how a surrogate for a biological agent, such as anthrax, might disperse throughout the nation’s largest rapid transit system as a result of a terrorist attack or an accidental release. As part of a multi-agency test sponsored by the Department of Homeland Security Science and...

Need to know more about nuclear forensics? Lab's analytical chemists have it covered

Feb. 18, 2016- 
Two Laboratory scientists have teamed with Australian colleagues to author an overview of nuclear forensics that is featured as the cover story for the Feb. 2 edition of Analytical Chemistry magazine.LLNL analytical chemists Mike Kristo and Ruth Kips, in collaboration with three researchers from the Australian Nuclear Science and Technology Organisation (ANSTO), wrote the article describing...

Lawrence Livermore researchers use seismic signals to track above-ground explosions

May 21, 2015- 
Lawrence Livermore researchers have determined that a tunnel bomb explosion by Syrian rebels was less than 60 tons as claimed by sources.Using seismic stations in Turkey, Livermore scientists Michael Pasyanos and Sean Ford created a method to determine source characteristics of near-earth surface explosions. They found the above-ground tunnel bomb blast under the Wadi al-Deif Army Base near...

Providing data for nuclear detectives

March 3, 2015- 
Fans of the popular TV series "CSI" know that the forensics experts who investigate crime scenes are looking for answers to three key questions: "Who did it; how did they do it; and can we stop them from doing it again?"The field of nuclear forensics, an important element of LLNL’s national security mission, has similar goals and uses similar techniques — but with even higher stakes."In...
