Description
Magnetic resonance imaging (MRI) are considered one of the most efficient and non-invasive methods of observing water content in permeable substances. MRI can visualize and quantify the movement of water in real time. In this study, MRI was used to observe the water penetration through clay. Furthermore, MRI can acquire three-dimensional data due to its radio-frequency signals from any orientation. The contrast of the images produced by MRI is a display of the fluid concentration. As such, any change in the contrast intensity is interpreted as a regional change in the concentration of fluid. This report summarizes the preliminary results from a series of experiments performed with an MRI. The primary goal of the study is to provide a non-destructive method to quantify the permeation of clay using different amounts of water to determine if the low-field MRI approach can be viable option when evaluating the development of storage containers. This investigation is motivated with the intent to develop better and more environmentally friendly containers used to store radioactive waste.

Development of a Low Field MRI-Based Approach for Observation of Water Penetration into Clay: Preliminary Results
