She was professor at the Utah State University and at the University of Applied Life Sciences and Natural Ressources in Vienna. With respect to the IRC it can be said that she was member from 1963 till 1971, which means that Inge Dirmhirn (together with J. Lenoble) was the first female member of the radiation commission.
