New model more accurately tracks gases for underground nuclear explosion detection

Scientists at Los Alamos National Laboratory have developed a new, more thorough method for detecting underground nuclear explosions (UNEs) by coupling two fundamental elements—seismic models with gas-flow models—to create a more complete picture of how an explosion's evidence (radionuclide gases) seep to the surface. Their findings will appear in today's edition of the journal Nature's Scientific Reports in a paper titled, "Radionuclide Gas Transport through Nuclear Explosion-Genera
