Decisions regarding radiological protection are informed by science, including its uncertainties, influenced by stakeholder concerns, driven by prevailing circumstances, and broadly based on values and judgments. However, the processes by which protection decisions are taken do not always sufficiently articulate the scientific and value-judgment elements on which decisions are based. To assist decision makers at all levels to further clarify the various aspects of their decisions, and to assist scientists and regulators in better understanding each other’s contributions to radiological protection decisions, the NEA Committee on Radiation Protection and Public Health (CRPPH) has held two workshops addressing science and values in radiological protection. This report summarises the discussions and conclusions of the first two workshops in this innovative series, and suggests the way forward in preparing the discussions at the third science and values workshop.
