Frequent Questions

Where are the RadNet monitoring locations?

RadNet air monitoring and sampling stations are located across the entire U.S, with at least one fixed-air monitoring station located in each state, the District of Columbia and Puerto Rico.

RadNet air monitoring locations were selected to function as a wide-area, nationwide monitoring network that provides optimum population and geographical coverage throughout the United States. There are monitoring locations in each geographical region and most major population centers.

The EPA also has an additional 40 portable air monitors which can be deployed during a radiological release. These monitors are used when higher density air monitoring is needed, usually near the source of a release of radioactive materials. The deployable air monitors are intended to be used to provide additional short-term air monitoring data.
