Abstract
Recently, the ICRP has recommended the use of a ‘Representative Person’ as a new basic recommendation to evaluate the dose of individuals with different characteristics, habits, and lifestyles. A dose assessment method in Korea is based on the Maximum Exposed Individuals (MEI) of a critical group, which has been adopted by the U.S. NRC. The MEI concept is more conservative than a ‘representative person’ is. Therefore, to set the modified parameters according to the new recommendation, we performed a sensitivity analysis of a dose assessment code’s input parameters as a preceding research. For the first step, we chose several qualitative parameters that occupy a relatively large part of a dose assessment. For a sensitivity analysis, we sampled the parameters with LHS, which is a Monte-Carlo method. A sensitivity analysis was performed to find how important these parameters are and to rank their importance. The sensitivity analysis of the parameters will be extended to all areas of an individual dose assessment. Then, more accurate and efficient values might be obtained for a dose assessment. The information of the dose obtained in this study might contribute to a basic tool for the optimization of radiation protection based on the new ICRP recommendation.
