Alexa von Wrangel is a PhD student at the Department of Radiation Physics at the University of Gothenburg. In her PhD project she is focusing on radiation safety during image-guided treatment of patients. The project is carried out in collaboration with researchers from the Department of Education, Communication and Learning at the University of Gothenburg. Her research interest concerns how staff members in the operating room attend to risks for radiation exposure and how they perform dose-reducing actions in their daily work. The over arching goal is to contribute with knowledge on how to improve work environment for the staff and to increase patient safety with respect to radiation.
