WASHINGTON - The US Navy on Tuesday recommended personnel and families stationed at two bases in Japan take precautions after detecting low-levels of radioactivity, including limiting outdoor activities.

"These measures are strictly precautionary in nature. We do not expect that any United States federal radiation exposure limits will be exceeded even if no precautionary measures are taken," the Seventh Fleet said in a statement.
