TOKYO — An American nuclear-powered submarine leaked radiation for more than two years, releasing the bulk of the material in its home port of Guam and at Pearl Harbor, Japanese and American officials said yesterday.
On August 1, the U.S. Navy notified Japan that the USS Houston had leaked water containing small amounts of radiation during three calls to the southern Japanese ports of Sasebo and Okinawa in March and April this year but caused no threat to people or the environment.
The U.S. Navy released a detailed chronology of the leaks over the past two years, showing that the cumulative radioactivity released was less than 9.3 micro curies — with 8 micro curies released in Guam alone. By comparison, according to the U.S. Environmental Protection Agency, the average amount of radioactivity in a smoke detector is about 1 micro curie, or 1 millionth of a curie.
