He slipped and succumbed from a burst of gamma radiation.  Wrenching it asunder with his bare hands, it took over a week for him to die.  He called this experiment "tickling the demon's tail."  A sphere just this size destroyed Nagasaki.  The Demon Core was being shipped out to Tinian for Bomb #4 when the Japanese surrendered.
