Photo: "Nuclear Archaeologists" Find World War II Plutonium



A plutonium sample (above right) found at a U.S. waste dump in 2004 is leftover from a batch used in 1945 for the world's first nuclear bomb test, a team of chemists announced in early 2009.

A clean up team unearthed the 13.5-ounce (400-milliliter) sample in a waste pit at the Hanford Nuclear Reservation in Washington, where it was sealed in a glass jar and enclosed in a safe (above left).
