Long-term Residents: The risks may be higher for U.S. citizens who reside for more than one year within 80 km of the Fukushima Daiichi Nuclear Plant. Out of an abundance of caution, we recommend that U.S. citizens who choose to reside for more than one year within 80 km of the Fukushima Daiichi Nuclear Plant consult with local authorities to receive current guidance on expected levels of radiation and recommendations for reducing exposure to radiation. In addition, pregnant women, children, and the elderly should avoid residing within 30 km of the Fukushima Daiichi Nuclear Plant.
