Today, Hanford is the most contaminated radioactive site in America—the site of a massive (and troubled) cleanup effort. Radioactive material is still accidentally leaking into the ground. Though Hanford’s plants routinely released small doses of radioactive material into the air, most of this damage came from an event in 1949 called Green Run.

Green Run was a secret Air Force experiment that released Hanford’s largest single dose of radioactive iodine-131. On the night of December 2, 1949, at the behest of the military, scientists at Hanford let 7,000 to 12,000 curies of iodine-131 into the air, where it rode the wind as far as 200 miles. For a sense of scale, the Three Mile Island nuclear power plant accident released an estimated 15 to 24 curies of iodine-131 and the Chernobyl accident 35 million to 49 million curies.

The Green Run stayed secret until the 1980s, when it was revealed by Freedom of Information Act requests from local newspapers. The military details are still classified. More than half a century later, suspicion and controversy continue to lurk around Green Run, especially among the residents who lived downwind of Hanford.

There’s still much that we don’t know about the Green Run, but here is what we do.

Hanford, Factory and Farm …….Hanford was always more than a production facility; it was also a research complex. Up to 1,000 animals were housed on a farm near reactor F for experiments on the effects of radiation. The animals included fish, dogs, pigs, sheep, and even alligators. Sheep, especially, were given feed with iodine-131, the same radioactive material that the reactors were discharging into the air…….http://gizmodo.com/the-secret-1949-radiation-experiment-that-contaminated-1707748721
