Frequent Questions

What is the EPA doing about tracking radiation in our environment from Fukushima?

The EPA’s radiation air monitoring system, RadNet, has not found 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.

The EPA continues to work with other Federal agencies, including the National Oceanic and Atmospheric Administration (NOAA), the Food and Drug Administration (FDA), and the Nuclear Regulatory Commission (NRC) to carefully follow the situation at Fukushima.
