Data on six experiments on contaminant mobility in soil as supplemental information of the publication "Quantitative tomography of contaminant phytomobilization: β+ emitters 83Sr and 86Y  as tracers of fission-product analog mobility"

by Jann Schöngart, Marcel Lindemann, Max Klotzsche, Karsten Franke and Cornelius Fischer, to be submitted to Journal of Hazardous Materials Advances. 

The data in this publication consists of:

µCT data

RossendorfSand_tvchambolle_uint16_2162x2170x1742_3.7308um:  µCT of a FeOOH-coated sand from Dresden-Rossendorf, Germany. voxel size = 3.3708 µm. Format: 3D-array of uInt16, x=1:2162, y=1:2170, z=1:1742.

Core_D_before_dissolution_2307x2329x1452_uint16.raw: µCT of a pure quartz sand from Hohenbocka, Germany ('glass sand HB04'). voxel size = 10.032 µm. Format: 3D-array of uInt16, x=1:2307, y=1:2329, z=1:1452.

Positron emission tomography data All PET data is stored as three-dimensional binary arrays of floats, with a voxel size of 1.15 mm.

Stored in [subset]_PET_Raw.zip: 

Uncalibrated positron emission tomography time series (decay corrected). Each image consists of two files - a header file (.hv) and the binary image file (.v). The header file contains information on how to read the binary file, as well as additional information.  Please note that not all of the metadata given in the header file (like timestamps, etc.) are generated automatically and not neccessarily accurate.

Stored in [subset]_PET_ScatterCorr.zip: 

The data of PET_Raw.zip, with the Scatter, Random and RandomMismatch-Corrections from STIR (Thielemans et al., 2012) applied.

The data structure is identical to [samplename]_PET_raw.zip.

Stored in [subset]_PET_ErrCorr.zip: 

*limErr.hv: Relative errors of the PET_raw data, calculated from count rates using poisson statistics. A value of 1 equals 100% error. The volumes are cut to the ROI. The data structure is identical to [samplename]_PET_raw.zip.

*lim.hv: Scatter-corrected data, with values of >100% error removed.

The project received funding from the BMBF, grant number 02NUK066A.
