Main Text
At the bottom of the poster, text reads: “The Manhattan Project launched the nuclear age and paved the way for future generations to live in a nuclear world. The reactor building where you are standing opened the door to this new age by industrializing the science that unleashed the energy held within the atom and made large-scale production of plutonium possible.

“The decision to use the atomic weapon is one of the most consequential decisions of the 20th century. Imagine the outcomes and consequences that President Truman reflected on when he debated the decision to us atomic bombs on Japan.
