What happens if air monitors report radiation levels outside of normal background levels?

RadNet near-real-time air data are screened at the EPA’s National Analytical Radiation Environmental Laboratory (NAREL) to identify anomalous readings. When an anomalous result is reported, the data are flagged for review by a trained EPA scientist.

In instances where further review of the near-real-time data is needed, air filter analysis from the monitoring location can present a more complete picture of the cause of the anomalous values.
