Update on Federal Radiation Milk Sampling

The U.S. Environmental Protection Agency is no longer conducting RadNet milk sampling. The U.S. Food and Drug Administration has the authority for food safety, including monitoring radiation in milk. Learn more about FDA’s Total Diet Study and Toxic Elements in Food and Foodware, and Radionuclides in Food programs.

EPA completed its final quarterly milk sample collection in April 2014 and the results from analyzing those samples, along with historical milk sampling results, will continue to be available on Envirofacts.

What is RadNet?

The nationwide RadNet system monitors the nation’s air, drinking water and precipitation 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.
