RadNet Sampling and Analyses Schedules
Under normal conditions, RadNet air monitors operate continuously and samples of air, precipitation and drinking water are analyzed on a routine schedule. In a radiological emergency, EPA may deploy teams to conduct air monitoring and environmental sampling. Learn about EPA’s role in radiological emergency response.

Routine Sample Analyses
RadNet Air Filter Inquiries
A RadNet air filter inquiry is initiated when there is potential for a release of radioactive materials to the air that could result in the presence of airborne radionuclides at low concentrations, or if low concentrations of radionuclides have been detected in the US or by an international agency. View the RadNet Air Filter Inquiry Log.
RadNet sampling and analysis are particularly useful when an event such as an explosion or fire sends significant levels of radionuclides into the air. Results of real-time data acquisition and subsequent sample analysis can provide critical information on the identity and concentration of radionuclides in air, precipitation and drinking water. Data from RadNet are useful in dose assessments, as health physicists estimate the immediate and long-term environmental and public health effects.
