Much of the radioactive waste that remains here is an unwanted by product of uranium purification conducted at the Mallinckrodt Chemical Works on North Broadway. In 1942, the St. Louis chemical manufacturer began refining uranium for the Manhattan Project, the secret wartime program to develop the atom bomb. The uranium used in the first atomic test explosion and the initial atomic attack on Japan was processed in St. Louis.

The first atom bomb used in actual warfare exploded over Hiroshima at 8:15 in the morning on Aug. 6, 1945. More than 100,000 people died, either instantly or of radiation sickness. The 2-kiloton bomb was nicknamed “Little Boy.” The ¬†annihilation would be repeated three days later on Nagasaki. Japan quickly surrendered.

Whether the atom bomb attacks saved more lives by bringing a rapid end to the war is still a matter of great debate. President Harry S Truman, a Missourian, claimed that using the bomb prevented what would have been bloody land invasion that could have cost the U.S. a million more casualties.

This much is known, Japanese civilians who survived the attack on Hiroshima say they didn’t hear any noise at the moment the bomb detonated. Instead, they describe a blinding light, disintegration, darkness, and fire.

In short, hell on earth.
