The map below provides links to RadNet individual air monitoring location webpages. Near-real-time air monitoring data are shown as graphs that are updated several times daily. Searchable current and historical monitoring data are available in the RadNet database in EPA's Central Data Exchange (CDX).

Below the map is a list of RadNet stationary air monitors by state, as well as precipitation and drinking water sampling locations that have reported data in 2015.
