[Pope Pius XII in the History of Radiology: St. Michael the Archangel Protector of Radiologists].

In 1933 the Professors of Genoa School of Medicine V. Maragliano, GB. Cardinale, and A. Vallebona proposed to designate Saint Michael the Archangel as Patron Saint and Protector of Radiologists. The proposal of Italian radiology scientists was immediately accepted by colleagues with great enthusiasm. A petition was then sent to Pope Pius XII to obtain official recognition by the Catholic Church. The choice of the Holy Archangel Michael was argued by the Professors because he is the Saint who, in religious iconography, is the one who wears armor, is the guardian of paradise, and leads souls to God. Moreover, the Saint represents the triumph of the Light of Good against the darkness of evil. On January 15, 1941, the Sacred Congregation of Rites issued the decree that constituted: "Sanctus Michael, Archangelus pro radiologis et radiumtherapeuticis patronus et protector declaratus".
