Frequent Questions

When is air data available to the public?

The near-real-time air monitoring data are continually reviewed by computer and are usually posted to EPA's RadNet Central Data Exchange (CDX) website within three hours of arriving at the laboratory.

If the results show an abnormality in radiation levels, EPA laboratory staff is alerted immediately and reviews the data to ensure that they meet quality control criteria before posting.

EPA scientists analyze RadNet air filters and cartridges. Data are posted in the RadNet Envirofacts database.
