Abstract

This study presents an advanced sampling evaluation method combined with Geostatistics and MARSSIM process for the estimation of the contamination level and uncertainty quantification. The developed evaluation method was applied for a final status survey after decommissioning the Uranium Conversion Plant. The evaluation results of the site generated 450 datasets with uncertainty from the Kriging, and the distribution was converted into a normal distribution, which can improve the reliability and reduce the required number of representative samples.
