XinhuaTrace amounts of radioactive Iodine found in U.S. drinking water
WASHINGTON, April 4 (Xinhua) -- Trace amounts of radioactive iodine has been found in drinking water samples in two northwestern U.S. states, but the levels detected have been far below levels of public-health concern, the U.S. Environmental Protection Agency (EPA) said late Monday.
According the EPA, Drinking water samples from two locations, Boise, Idaho and Richland, Washington, showed trace amounts of Iodine-131 -- about 0.2 picocuries per liter in each case.
"An infant would have to drink almost 7,000 liters of this water to receive a radiation dose equivalent to a day's worth of the natural background radiation exposure we experience continuously from natural sources of radioactivity in our environment," the EPA said in a statement.
