Excellent research must assume responsibility. Responsibility in the research process means ensuring that research findings are acquired legitimately and that scientific work meets high quality standards. With respect to research topics at Jülich, responsibility applies to the legacy of the former nuclear research centre, the dismantling of the former research rectors Merlin and Dido, and waste from medical research with radionuclides. However, it is not just about responsibly dealing with the nuclear legacy safely and competently. Today, researchers also address ethical issues associated with their research: whether it be in neuroscience, plant research and biotechnolgy or in energy research.
