INTEGRATION OF GEOLOGIC AND HISTORIC ASSESSMENTS INTO THE MARSSIM APPROACH AT COMPLEX SITES

摘要

Difficult sites contaminated by radiological wastes require adequate assessment of their geology and use history. Evaluations limited to the near surface may not adequately account for the original placement of contaminants nor their fate and transport through time until remediation. Evaluation of the exposed remedial surface for possible contaminant transport routes into the subsurface helps assure adequate evaluation of the release criterion for the subsurface soil and rock. This paper cites the added value in conducting some surveys not specified by standard radiological practice.
