Harry Daghlian had his body exposed to plutonium. He organs and tissues dissolved but in their place he gained an extended life. He has a half-life of 24,000 years.
Harry was placed in a prison to protect his radiation from affecting others. Enrico Fermi was the only person who visited him. He eventually rigged a machine for Daghlian to leave the solitary confinement and move about in his suit.
Dr. Daghlian plugged Franklin D. Roosevelt (The Manhattan Projects) in a mainframe creating the world's first Artificial Intelligence.
When his long-time friend, Enrico transformed into his true alien form and attempted to sabotage the project for expanding earth onto other planets, Daghlian killed Enrico with a radiation blast.
