The unit evaluates the potential risks of ionizing radiation on health and conducts radiation risk assessments for occupational, accidental, medical, or space radiation exposure. The work is performed in close collaboration with the European Commission, the European Space Agency, Belgian and European Universities, and hospitals and research institutes. Besides this, Sarah is a guest-professor at Ghent University and maître de conférence at the University of Namur. She is also a member of the Belgian delegation at United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and of the High Council for Health. In 2018, she received the BeSpace personality of the year award and was recognized by Femmes d’Aujourdhui as one of the 85 women that make Belgium move. She had the immense pleasure to go to the Belgian Princess Elisabeth station in Antarctica last winter to conduct space-related health studies in extreme environment.
