Case study of soil characterization techniques at decommissioning nuclear power plants

In order to minimize this maintain decommissioning project schedule, effective characterization of the soil and site of the contamination is needed. In this paper, describes the investigation results for the characterization techniques and overseas cases in order to effectively perform the soil characterization. This paper describes four types of the techniques for characterization of soils. Among these, in situ Gamma Spectroscopy is generally used for decommissioning. In the case of the overseas, the characterization was performed by using the above technologies.
