internal exposure facility Facility for studying radionuclides availability, transfer and migration Paul Schofield This facility at SCK-CEN Mol is dedicated to studying the behaviour of radionuclides in biological and environmental systems, including their availability, transfer and migration in plants, soils and organisms. It supports research on radionuclide biokinetics and the development of environmental transfer models relevant to nuclear waste management and radioecology. Access requires security verification by the Federal Agency for Nuclear Control, a medical examination, and a safety quiz. Located at SCK-CEN.
