Radioactive waste results from many different activities in health care, industry, research, and power production. All such waste must be managed safely, with the protection of human health and the environment as the highest priority. After decades of research, the international scientific community is now confident that placing high-level radioactive waste in deep geological repositories (DGRs) is both safe and effective. The government of each country has the absolute right and responsibility to implement the energy and environmental policies it believes are best. In the case of the disposal of radioactive waste, it is paramount that these debates should be informed by objective facts. This report therefore aims to provide the general reader with the current state of knowledge with regards to the management of high-level radioactive waste in DGRs.
