Navy sub leaked radiation

WASHINGTON (CNN) - Water with trace amounts of radioactivity may have been leaking for months from a U.S. Navy nuclear-powered submarine as it traveled around the Pacific to ports in Guam, Japan and Hawaii, Navy officials told CNN Friday.

The leak was found on the USS Houston, a Los Angeles class fast attack submarine, after it came to Hawaii for routine maintenance last month, Navy officials said.

Navy officials believe the amount of radiation leaked was virtually undetectable. But the Navy alerted the Japanese government because the submarine had been docked in Japan.
