RadMap Monitor

Desktop Information on Radiation Monitors Nationwide


Designed for use by emergency responders, RadMap is an interactive desktop tool featuring a nationwide GIS map of long-term radiation monitoring locations across the United States with access to key information about the monitor and the area surrounding it.

In the event of a radiation release, RadMap can help emergency responders collect information, develop assessments, and determine the placement of deployable monitors. Desktop access could be critical should other systems fail in an emergency.

Users can highlight an area to identify key information about the monitor and to characterize the monitor location. RadMap provides easy access to:

Who is protecting you

State and Local Authorities

Most States and some local governments maintain various types of monitoring capability, which surveys radiation and radioactivity in the environment.  Monitor information for these states and local governments can be found on the respective health department web sites.

U.S. Nuclear Regulatory Commission (NRC)

U.S. Nuclear Regulatory Commission (NRC) requires licensees to monitor the discharges and analyze nearby environmental samples to ensure that the impacts of plant operations are minimized. These measures ensure that the permitted discharges result in very small doses to members of the public living around nuclear power plants.

U.S. Environmental Protection Agency (EPA)

RadMap is a national GIS mapping tool of fixed monitoring stations that collect air, precipitation, drinking water, and milk samples for analysis of radioactivity. The RadMap program identifies government monitors in each State regardless of the ownership.

Department of Homeland Security (DHS), Federal Emergency Management Agency (FEMA)

FEMA evaluates both the state and local off-site emergency response plans and the off-site radiological emergency preparedness exercises that are conducted at each commercial nuclear power station every two years.

U.S. Department of Energy (DOE)

The DOE establishes nuclear safety and environmental protection requirements and expectations for the Department to ensure protection of workers and the public from the hazards associated with nuclear operations, and protection of the environment from the hazards associated with all Departments through a combination of public rules and DOE directives.

Protecting yourself

Protecting yourself and your family from any threats whether manmade or a natural disaster is a shared responsibility and everyone has an important role to play. There are a number of actions you can take to ensure your family is prepared for an emergency of all kinds - Local, State, and Federal.

Governments provide advice and recommendations to help in case of an emergency. Please contact your local for information.


For first responders, RadMap monitoring locations and data currently include monitors from DOE facilities, NPPs, RadNet, Desert Research Institute, and states. RadMap also features:

RadMap helps fulfill one of EPA’s critical homeland security’s responsibilities under the NRP and addresses recommendations made by both the Conference of Radiation Program Directors and EPA’s Science Advisory Board (SAB).
