The Community Environmental Monitoring Program (CEMP) is a network of 29 monitoring stations located in communities surrounding and downwind of the Nevada National Security Site (NNSS), formerly the Nevada Test Site (NTS), that monitor the airborne environment for manmade radioactivity that could result from NNSS activities. The CEMP is a joint effort between the Department of Energy's National Nuclear Security Administration Nevada Site Office (NNSA/NSO), and the Desert Research Institute (DRI) of the Nevada System of Higher Education.
