Frequent Questions

Why aren't the results for my location up to date? Why are there gaps in data?

The EPA's RadNet monitors are highly sophisticated devices that occasionally require maintenance and repair. While monitoring equipment is serviced, results are unavailable and may result in reported data gaps. Shortly after RadNet monitors are returned to normal operation, results should begin to appear.

Also, all data collected by the RadNet air monitors are reviewed for anomalies before they are publicly available on the EPA’s website. Anomalous data are reviewed by EPA scientists, and, if validated, will later appear on the website.

Near-real-time air monitoring data are posted to the RadNet website six times daily. There may be a slight delay in data availability due to server or network issues. Once the issues are resolved, data will be refreshed as soon as possible.
