Frequent Questions

Where can I find beta monitoring data?

Reviewed and approved near-real-time beta air monitoring data are available in the RadNet Database in EPA's Central Data Exchange (CDX). Note that there may be large gaps in these data due to local radiofrequency interference. For this reason, near-real-time beta monitoring graphs are not displayed on the RadNet site.

Gross beta activity levels from laboratory analysis of air filters are available in Envirofacts. Envirofacts houses sampling data for air filters and cartridges, precipitation, milk and drinking water.
