Radiation Emergencies
Emergency Response:

Radiological Emergency Response Team

Emergency Preparedness
and Response

The Radiological Emergency Response Team (RERT), based in EPA's Office of Radiation and Indoor Air and EPA’s Regional offices, responds to emergencies involving releases of radioactive materials. Working closely with EPA's Superfund Program as well as federal, state, and local agencies, the RERT responds to emergencies that can range from incidents at nuclear power plants, to transportation accidents involving shipments of radioactive materials, to deliberate acts of nuclear terrorism.

What does RERT do during a radiological emergency?

The RERT coordinates or assists federal, state, tribal, and local response efforts before, during, and following a radiological incident by providing support in various forms:

You can learn more about EPA's role in responding to radiological emergencies from the How We Respond pages.

How quickly can the RERT respond?

Field teams (teams that go to the scene of the emergency) will deploy as quickly as possible after notification. Shortly after arriving at the scene, the RERT begins environmental measurement and guidance activities. They begin monitoring, sampling, and laboratory analysis. They also advise state and local authorities on protecting local residents from exposure to harmful radiation levels.

If needed, the RERT can drive its mobile emergency response laboratory and support equipment to any site in the United States within 2 to 4 days.

How does the RERT prepare for emergencies?

To maintain readiness, the RERT works with other federal agencies and state and local governments to develop and fine tune plans for responding to radiological and nuclear emergencies. To test these plans, RERT personnel annually update their multidisciplinary skills, conduct emergency response exercises, and provide training to other organizations charged with responding to radiological emergencies.

How big is the RERT?

There are approximately 45 field-deployable members of the RERT stationed at EPA's facilities in Montgomery, Alabama and Las Vegas, Nevada. Additional support personnel are located at EPA headquarters in Washington, DC, and EPA's 10 regional offices.

EPA can send a few specialists or the entire RERT to an emergency site. Headquarters RERT members support field operations activities from the Agency's Emergency Operations Center in Washington, DC and other coordination centers. Headquarters members also serve on the Advisory Team for the Environment, Food and Health, which assesses emergency monitoring data and develops protective action recommendations.

What kinds of specialists are in the emergency response program? 

Radiological emergencies require a multi-disciplinary team which can track, contain, and clean up a radioactive release, while protecting people and the environment around the emergency site. EPA's emergency response personnel include scientists and engineers, health physicists, laboratory staff, and other emergency response specialists:

Scientists and Engineers

These specialists monitor, measure, and track the type and amount of radiation released from an accident. They conduct on-site sampling and analyze the air, water, and soil to identify the kinds of radionuclides present. Then they send field samples to EPA's National Analytical Radiation Environmental Laboratories for additional analyses and verification of on-site results.

Health Physicists

HPs study the effects of radiation on people and the environment. They recommend ways to protect both during an incident.

Laboratory Staff

Laboratory staff analyzes the samples taken in the field by the scientists and engineers. They identify the kinds and amount of radionuclides in the environment around the incident.

Other Radiological Emergency Response Specialists

EPA's emergency response team includes other specialists who provide communications, logistical, and administrative support.

What types of equipment and vehicles does RERT use?

Class C Equipment

The RERT provides protective equipment and personal dosimeters to protect the health and safety of members in the field. It also has handheld equipment used to survey the emergency area:

In addition, the RERT has both laboratory and emergency management vehicles:

RERT Vehicles

These mobile facilities can be driven to the scene of an emergency. Local, satellite, and Internet-based communication capabilities help them keep in touch with response personnel from other agencies.

What role do EPA's other radiation facilities play?

The National Analytical Radiation Environmental Laboratory (NAREL) in Montgomery, Alabama, and the National Center for Radiation Field Operations (NCRFO) in Las Vegas, Nevada, provide monitoring and assessment services at the lab and at the scene of an accident. Mobile laboratories are equipped for radioanalytical services, including gamma spectroscopy, alpha/beta analyses, and liquid scintillation analyses. RERT field staff send samples requiring more extensive analyses back to NAREL.
