Preventing collateral damage in cancer treatment

October 23, 2023 • LIVERMORE, Calif. — Using a simple concept and a patented Sandia sensor that detects radioactive materials, a team at Sandia National Laboratories has developed a patch to stop damage to healthy tissue during proton radiotherapy, one of the best tools to target certain cancerous tumors. “This is an important need,...

Radiation-detecting plastic gets ingredient to stay in the clear

April 30, 2020 • LIVERMORE, Calif. — Researchers at Sandia National Laboratories have identified a straightforward change to the formula for radiation-detecting plastic. The change prevents “fogging,” which reduces the lifetime of the plastics used to detect nuclear material transiting through the U.S. Department of Homeland Security’s radiation detectors. The change also fits well...

New radiation detectors developed at Sandia used for New START inspections

February 1, 2018 • ALBUQUERQUE, N.M. — Sandia National Laboratories designed, tested and delivered new radiation detection equipment for monitoring under the New START Treaty. Defense Threat Reduction Agency inspectors recently used this equipment for the first time in Russia for a New START inspection. New START, or the New Strategic Arms Reduction Treaty,...

MINER shines in urban emergency response exercise

October 30, 2014 • Mobile imager of fast neutrons spots radiation source at a distance and through shielding LIVERMORE, Calif. — A nuclear device has been hidden in a high-rise building in a major metropolitan area. Emergency responders have intelligence that narrows down the location to a single city block, but it isn’t safe...

Colorful light at the end of the tunnel for radiation detection

June 29, 2012 • LIVERMORE, Calif.— A team of nanomaterials researchers at Sandia National Laboratories has developed a new technique that could make radiation detection in cargo and baggage more effective and less costly for homeland security inspectors. Known as spectral shape discrimination (SSD), the method takes advantage of a new class of nanoporous...
