EPA's RadNet Data

EPA's nationwide radiation monitoring system, RadNet, consists of two components. First, stationary and deployable air monitors measure radiation 24 hours a day, 7 days a week. The map below provides monitoring results as graphs that are updated several times daily. You can also search the RadNet database in EPA's Central Data Exchange (CDX) to find monitoring data. Second, EPA samples precipitation and drinking water on a routine schedule and tests them for radiation in a laboratory. The latest RadNet sampling results are available in Envirofacts.

More Info

The interactive map below provides access to monitoring data. Point your mouse at the colored dots to see the data for a particular location. You can also access the results through the list of monitoring locations by state.
