Site Characterisation
The links between site characterisation and the biosphere component of the assessment, including guidance on protocols for obtaining data, have been considered in the Theme 3: Site Characterisation, Experiments and Monitoring report. Experience with characterisation at particular sites is now being gathered from those who have done the work, in terms of recognition of difficult areas as well as successes. It is hoped that this can be useful to others.
The next step being considered is to share information on how the obtained data is presented and interpreted, for the purpose of demonstrating an understanding of the site, and for use in developing scenarios for possible site evolution, and for evaluation of these scenarios via conceptual and mathematical models for site behaviour. These models can then be used to justify assumptions for assessment models which address radionuclide migration and accumulation in the biosphere and radiation exposure of humans and other biota.
The site characterisation work may also directly supply data for input to existing models for assessing particular scenarios. Following the flow of information and the management of data in the entire process is all part of the challenge, especially if it can be intelligently linked to characterisation for operational phase environmental impact assessments. The experience gained and shared is intended to help make continued site investigation work as effective and efficient as possible.
