RadNet monitoring data is available to the public at several online locations.
- The EPA’s RadNet website includes near-real-time gamma gross count rate air monitoring data and air filter analysis results for over 135 monitoring locations nationwide. Exposure rate data are shown for some RadNet air monitoring locations, including the ten most populated U.S. cities. Near-real-time air monitoring data are also available on the RadNet website for download in CSV (comma-separated value) format for each individual monitoring location.
- The RadNet Central Data Exchange (CDX) is a searchable website for specific near-real-time air monitoring results. Users can search for near-real-time results from RadNet air monitoring locations for a specific time period. The RadNet CDX query page also allows users to view and download gamma gross count rate results subdivided into contiguous channel ranges.
- Envirofacts is a searchable digital repository of RadNet laboratory analysis results of air filters (from each RadNet air monitor), drinking water sampling, and precipitation sampling. Envirofacts also includes historical sampling analysis results for milk sampling. *
- Environmental Radiation Data (ERD)Journal reports were published quarterly by the EPA's National Analytical Radiation Environmental Laboratory (NAREL) through the end of 2016. These reports include results for air, drinking water and precipitation samples collected as part of the EPA's RadNet monitoring program. To view current RadNet monitoring data, please visit the EPA's RadNet website or the online resources listed above.
* As of April 2014, the EPA no longer conducts RadNet milk sampling. The U.S. Food and Drug Administration (FDA) has the authority for food safety, including monitoring radiation in milk.
