The Radiation King is one of several Matt Groening references in the Fallout series. The Radiation King refers to Homer Simpson's childhood television set as seen in episode 10 of season 06, "Grampa vs. Sexual Inadequacy". Once young Homer Simpson reached adulthood, he felt it best to move on from The Radiation King and provide his family with the mighty, Carnivale found only at the outlet mall in Ogdenville.
The Radiation King TV sets that are found in the pre-War theme as well as throughout the wasteland are identical to the real world television set, The Philco Predicta, which was the most iconic television set of the 1950s.
