Planning of remediation of legacy sites and contaminated areas arising in unplanned situations needs to take account of the management and regulation of radioactive wastes arising. However, these wastes commonly present unusual characteristics which were not accounted for in design and development of national radioactive waste management strategies nor the corresponding regulatory frameworks. All these activities need to be coordinated, accounting for exposure conditions at a site and in its continuing management. This panel will consider these issues, taking into account developments in guidance on the application of international recommendations to different exposure situations and practical experience at example sites.
