Fukushima Information and Resources

EPA’s air monitoring data have not shown any radioactive elements associated with the damaged Japanese reactors since late 2011, and even then, the levels found were very low—always well below any level of public health concern.

We are providing the following links to the most current information from trusted scientific organizations that continue to monitor the situation:

What is RadNet?

The nationwide RadNet system monitors the nation’s air, drinking water, precipitation, and pasteurized milk to determine levels of radiation in the environment. RadNet sample analyses and monitoring results provide baseline data on background levels of radiation in the environment and can detect increased radiation from radiological incidents.
