The covert movement of special nuclear material or weapons into populated areas represents possibly the greatest threat to the security of our world. Radionuclide detection and identification systems are required to effectively detect or deter this threat by recognizing the presence or movement of radioactive material across borders, into government buildings, at large public gatherings and much more. The Stride system was designed for this purpose.
