This episode was likely inspired by the Goiania accident in Brazil. An unsecured radiotherapy source was stolen from an abandoned hospital site in the city. It was subsequently handled by many people, resulting in four deaths. About 112,000 people were examined for Cesius 137 contamination and 249 of them were found to have been contaminated. One of the four man that found the material, Odesson Ferreira described the moment as, "I fell in love with death's glow".
