Christopher Rääf serves as Professor in Medical Radiation Physics and Assistant Head of Department at the Department of Translational Medicine, Faculty of Medicine, Lund University. Based at the Malmö campus, his work bridges academic leadership with cutting-edge research in radiation safety and emergency response, maintaining active roles in institutional governance and national security initiatives. His research spans Radiation Physics, Dosimetry, and Radiological Emergencies, with emphasis on practical applications like using table salt (NaCl) for retrospective dose assessment in medical imaging and nuclear incidents. He investigates radionuclide behavior from facilities such as the European Spallation Source (ESS), develops Bayesian methods for radiation source localization, and contributes to national civil defense strategies against radiological threats through policy advocacy. Analysis of his recent publications reveals a cohesive trajectory toward deployable solutions for radiation emergencies—prioritizing accessible materials (e.g., salt pellets), environmental monitoring of nuclear facilities, and cross-disciplinary integration of medical physics with civil security. His work consistently addresses real-world implementation challenges in dose assessment and emergency preparedness. Professor Rääf leads significant research funding from the Swedish Radiation Safety Authority and Swedish Civil Contingencies Agency, including projects on Small Modular Reactor emergency protocols (2024–2027) and portable OSL dosimetry systems (2022–2026). His supervision portfolio includes three PhD candidates: Karampiperi, M. (OSL dosimetry), Dvornik, A. (radiation source localization), and Wallin, J. (Bayesian inference methods). He directs critical infrastructure including the Alpha and Gamma Spectrometry Laboratory and the Lund Luminescence Laboratory for Dosimetry, enabling advanced capabilities in radiation measurement, environmental sampling, and emergency response prototyping across medical and national security contexts.
