OAK RIDGE, Tenn. (AP) — Fallout from Japan's nuclear disaster has arrived in Oak Ridge, but an expert says it does not pose a health threat.
According to information posted online by the Environmental Protection Agency, radioactive I-131 was found in samples taken at three Oak Ridge sites on March 24.
Those levels were 17.7, 18.3 and 13.4 picocuries per liter. They are similar to levels found in Alabama and Georgia but lower than samples taken in Washington and Idaho.
Oak Ridge scientist Owen Hoffman is an expert in assessing radiation risk. He told the Knoxville News Sentinel the local levels are still about five times lower than what was measured after the 1986 Chernobyl disaster.
He said it is too early to know if the fallout levels will go up or down.
