Observation of 22Na+ - Diffusion in Opalinus Clay using Positron Emission Tomography (GeoPET)
<p>Clay rocks are one potential host material for nuclear waste deposits, because of their extremely small particle sizes cause low permeablility and high adsorption capacity. Molecular diffusion is the dominating transport process and therefore relevant for safety assessment.</p> <p>We applied positron emission tomography (PET) for investigating diffusion of <sup>22</sup>Na<sup>+</sup> in Opalinus clay rock. This enables to derive diffusion parameters on the macroscopic scale of drill cores (diameter 100 mm), and thus to consider effects of anisotropy and heterogeneities. This method is complementary to laboratory measurements with common diffusion cells, which can hardly elucidate such macroscopical spatial effects.<br> Here, we present the measuring data as motion picture. The underlying PET-data are 20 scans over a period of 143 days after injection of synthetic Opalinus pore water, labelled with Na-22, into an axial blind hole.</p>
Observation of Reactive Transport in Soil Columns with Positron Emission Tomography (GeoPET)
<p>Here we investigate reactive transport in soils with GeoPET as quantitative spatiotemporal molecular imaging method. As PET directly yields tracer concentrations, the data can be utilised for parameterization and validation of reactive transport computer models.</p> <p>Artificial soil columns (sand/silt/clay/Goethit, length 90 mm, diameter 40 mm) have been prepared under CO<sub>2</sub>-atmosphere. Four different experiments on one and the same soil column are shown as motion pictures from the GeoPET-observations:</p> <p>1) Injection of water, labelled with [<sup>18</sup>F]KF, into the CO<sub>2</sub>-saturated column</p> <p>2) Conservative transport of [<sup>18</sup>F]KF solution through the water-saturated column</p> <p>3) Injection of the reactive tracer [<sup>64</sup>Cu]Cu(MCPA)<sub>2</sub> into the unconditioned water-saturated column</p> <p>4) Injection of the reactive tracer [<sup>64</sup>Cu]Cu(MCPA)<sub>2</sub> into the preconditioned column.</p> <p> </p> <p>The study was supported within the framework of the priority program “Biogeochemical Interfaces in Soil” by the German Science Foundation (DFG SPP 1315: KE508/19 and LI872/5).</p> <p> </p> <p>References:</p> <p>Kulenkampff, J., Zakhnini, A., Gründig, M., and Lippmann-Pipke, J.: Quantitative experimental monitoring of molecular diffusion in clay with positron emission tomography, Solid Earth, <strong>7</strong>, 1207-1215, 2016.</p> <p>Kulenkampff, J., Gründig, M., Zakhnini, A., Gerasch, R., and Lippmann-Pipke, J.: Process tomography of diffusion, using PET, to evaluate anisotropy and heterogeneity, Clay Miner., <strong>50</strong>, 369–375, 2015.</p> <p>Kulenkampff, J., Gründig, M., Zakhnini, A., and Lippmann-Pipke, J.: Geoscientific process monitoring with positron emission tomography (GeoPET), Solid Earth, <strong>7</strong>, 1217–1231, 2016.</p> <p>Zakhnini, A., Kulenkampff, J., Sauerzapf, S., Pietrzyk, U., and Lippmann-Pipke, J.: Monte Carlo simulations of GeoPET experiments: 3D images of tracer distributions (<sup>18</sup>F, <sup>124</sup>I and <sup>58</sup>Co) in Opalinus Clay, anhydrite and quartz, Comput.
