[en] This comprehensive report for the Swiss Federal Office of Energy (SFOE) summarises the results of a literature study on the marking of repositories for radioactive wastes. Knowledge gained and ideas discussed in Switzerland on the subject are collated and discussed. Various associated topics such as safety, risk and marking technologies are examined. 28 topics in six thematic blocks are presented and discussed. Not only marking concepts are discussed, but also questions on human and society-related factors, traditionalising information transfer and susceptibility to wrong interpretation are examined. The author is of the opinion that no reusable materials be used either in the repositories themselves or for their marking in order to help prevent future generations coming into contact with the dangerous wastes
