When you hear the word “nuclear”, you might think of nuclear family, nuclear power, nuclear bomb, or nuclear accident.  Well, when you think of nuclear accidents, most of us go right to Chernobyl or Three Mile Island or maybe the most recent Fukushima incident in 2011.  But not too many know about the other nuclear incident that happened on U.S. soil.  As a matter of fact, it’s not just another accident in history, it’s the largest radioactive spill in U.S. history altogether, and it took place only 3 months after the Three Mile Island incident.  Find out where this spill took place, as well as what the cleanup efforts were like on this episode of The Missing Chapter.
