Frequent Questions

What is FRMAC and how is EPA Involved?

During a major radiological emergency, the Federal Radiological Monitoring and Assessment Center (FRMAC) is the control point for the federal assets involved in monitoring the potential impacts of the incident (including specialized equipment, emergency response personnel, and scientific experts). By providing environmental radiological data to emergency responders, the FRMAC assists state, local and Tribal governments in their mission to protect the health and well being of their citizens. EPA would support the FRMAC by, among other things, providing field teams to collect environmental monitoring data, supplying RadNet data, and providing radiation experts. EPA is also a part of the Advisory Team for Environment, Food, and Health, which works with the data collected by the FRMAC to interpret the Protective Action Guides (PAGs) for a specific site.

Upon request, the Department of Energy (DOE) is initially responsible for establishing the FRMAC. As the incident evolves and the focus moves from immediate emergency response needs to the long term environmental impact, EPA takes over FRMAC leadership.
