The aim of the article is to present a phenomenon of the sexualization of an atomic bomb in the popular culture of the 1940s and the 1950s in the United States. On the basis of sociological and cultural studies, the author lists the functions of this phenomenon. Furthermore, he uses the examples of press reports and popular cinema to indicate that the sexualization of the atomic bomb resulted from fear of sterilization and assimilation of soldiers coming back from the front. The analysis concerns the film I Married a Monster from Outer Space (1958). The author proves that science fiction films conceptualize social concerns, and accustom the viewers with atomic tension by means of appropriate narratives.
