Provisional Data Notice
It is the intent of the CEMP to provide to the public accurate, near real-time monitoring data through this web site. However, it should be noted that these data are provisional and therefore may be subject to change. Provisional data may be adjusted for various reasons including disruption of sensors, instrument calibration, equipment failure, and problems with data transfer. These data are not valid until thoroughly reviewed and evaluated by the Desert Research Institute. Data users are cautioned to carefully consider the provisional nature of this information before any application, particularly for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these provisional data may be obtained by contacting the Western Regional Climate Center at firstname.lastname@example.org or by calling (775) 674-7010.
Data Collection Program
The Community Environmental Monitoring Program (CEMP) is a network of monitoring stations located in communities surrounding and downwind of the Nevada National Security Site (NNSS) that monitor the airborne and groundwater environments for manmade radioactivity that could result from NNSS activities. The CEMP is a collaborative effort of the Department of Energy's National Nuclear Security Administration Nevada Field Office (NNSA/NFO), and the Desert Research Institute (DRI) of the Nevada System of Higher Education.

Potential downtime CEMP data collection Servers will be reconfigured on December 27 and 28. Web updates may be sporadic during this period, but will be back online as soon as possible. No changes are expected at this time to any urls or content.
UPDATE: A data processing problem has been identified and is being worked on. Station data may update sporadically during the next few days.
- Updated Scheduled Calibration Tests for March, 2017.
- Third Quarter 2016 Air Sampling and TLD Results are now available.
CEMP response to US Ecology fire
Oct 28 2015
In order to support the state's efforts in responding to the fire at US Ecology, the CEMP proactively collected filter samples from its low-volume air samplers located in Amargosa, Beatty, and Sarcobatus Flat. Filter analysis was carried out by UNLV's radioanalytical laboratory. Gross alpha and beta analysis and gamma spectroscopy analysis did not detect any radiation levels above background.
