For both aspects of the disposal question discussed in the paper, the aim is not only to quantify the issues, but also to provide a perspective by giving appropriate comparisons.
These comparisons come from other parts of the nuclear fuel cycle, from other areas of hazardous waste management or from other practices exposing individuals to risks.
Emphasis is placed upon the linkage between initial considerations of the potential hazards of wastes and final conclusions concerning the actual consequences (e.g. doses or risks) to humans from repositories.
In addressing the question, « How hazardous are radioactive wastes ? », the paper distinguishes between subjective and objective hazards and then quantitatively considers hazard potential expressed as activity level and as toxicity.
In the section on safety requirements on radioactive waste repositories, a range of topics is considered.
These include identification of key safety issues, alternative measures of safety, setting appropriate safety levels, and defining compliance requirements.
The following list of conclusions is drawn from the paper.
Radioactive wastes are not unique in their total or specific radioactivity or their toxicity ; neither do they present a unique problem with respect to their hazardous lifetimes.
Radioactive wastes are unique in that the public perception of the hazard presented differs enormously from the actual hazard. (...)
