Teo told parliament that the U.S. government informed Singapore that the cumulative amount of radioactivity that could have been leaked by the Houston when it visited Changi Naval Base on Sept. 22 to 26, 2006, was only about 0.095 microcurie.
"The United States indicated that this was less than the amount of radioactivity found in a common smoke detector," he said, adding that it has also assured that it "would not have any adverse effect on human health, marine life or the environment."
