National Security Sciences at ORNL

Sarah Walters is using her degrees #anthropology with a focus in #archaeology to lead the team working on Population Density Tables. She says she was "drawn to the field of anthropology because there are still so many unanswered questions about past peoples that lived prior to any written records, and I also had the opportunity to learn about modern people, places, cultures, and traditions, as well." Sarah uses many skills from her education in her work now, such as Geographic Information Systems (GIS), Remote Sensing and Satellite Imagery, and scientific writing. She learned additional skills while on-the-job at ORNL, including basic coding, imagery analysis, proposal and scope writing, and more administrative skills which includes understanding and managing finances, being an effective leader, and planning out tasks and deliverables every year.

Where people are across the world is an important part of data used to #securethenation. One of the #datasets created at ORNL is Population Density Tables. Using open-source information, researchers capture human dynamics around the globe and across a wide range of functions and activity-spaces. This data is used to understand and report the typical density of persons per 1000 square feet in buildings or other facilities during daytime, nighttime, and during morning and evening transitional periods. PDT data is foundational across applications, for example in understanding when and where people may be during crisis events and aiding in disaster response. PDT is also a critical input in ORNL's #LandScan HD gridded population model.

#Nuclear and #radioactive material is most vulnerable during transportation. ORNL opened the Global Evaluation, Analysis, Research, and Security—or, GEARS—Facility, enabling new research, development, and testing of security equipment. GEARS builds on ORNL’s science expertise in #cyber resilience, remote sensing, data analysis, and #nonproliferation to advance the state of the art in vehicle and transportation security.

Protecting #radioactive and #nuclear material happens wherever the material is. Our experts develop technologies to strengthen international safeguards and security. You might be surprised what kinds of experts this includes: all types of #engineers, cybersecurity professionals, policy professionals, and so much more.

Through its commitment to international #nuclear #nonproliferation, the U.S. maintains a constant vigilance aimed at reducing the threat of nuclear and radiological terrorism worldwide. With extensive research into both basic and applied #uraniumscience, ORNL is uniquely positioned to contribute its comprehensive capabilities toward advancing the U.S. nonproliferation mission. https://bit.ly/402SauU

Karlyn Harrod merges a love for #math and #health to create global models of disease. Using computers, Karly scans large amounts of reports to pull out data she needs to create her models. "I am particularly excited about this work, as data availability is a challenging area in the disease modeling world." ORNL has a team of researchers who model impacts to populations across the world, including health challenges, reasons to relocate, or the built environment. This data helps decision makers understand changes to our world and #securethenation through mitigation strategies. Read more about Karly's journey to ORNL: https://bit.ly/3CNaFKU

Our hearts are in our work to #securethenation using science-backed research and technology that provide data driven, time-critical mission support to prepare for and respond to threats and crises from natural, technological, and manmade disasters from local to global scales.

Several opportunities for #nonproliferation professionals at various career levels to join a cutting-edge research mission. Support the #DOE and #NNSA in efforts to control and reverse the international proliferation of #nuclear, chemical, biological, and missile technologies and programs that may support weapons research, development, and/or production.

Thanks to Emily C. and WBIR-TV for coming to ORNL to learn about a different way to use #Dopplar radar data for non-weather events. Check out Michael Benson sharing how this data could be used to track fire plumes or explosions and have a place in #emergencyresponse.

We #lovedata coming from various countries who participate in a global network to to detect and deter nuclear material smuggling. Over 90 countries actively search for lost or stolen material using radiation portal monitors that scan people, cars, trucks, trains and luggage at airports, seaports, border crossings and other international checkpoints. To keep the portals maintained and running, ORNL uses #AI to enhance network effectiveness and get the best performance possible of the equipment. Read more -> https://lnkd.in/eG4gd25n
