GEOMIND-R: Audited Database of Caesium and Strontium Uptake and Immobilisation in Geopolymers

An audited, provenance-tracked meta-analysis database of caesium and strontium uptake (adsorption) and immobilisation (leaching) in geopolymers and alkali-activated materials, compiled and source-audited from the published literature. The database is organised as two pools that are audited separately and never merged, because they measure opposite-signed targets: Pool A (adsorption, 141 rows / 14 sources) records how much cation a material removes from solution (higher is better), and Pool B (immobilisation, 73 rows / 10 sources) records how well a doped-in nuclide is retained under leaching (direction depends on the metric). Every value was checked against its primary published source before inclusion; roughly a third of candidate rows failed that audit and are recorded — each with the reason — rather than silently dropped. The bundle includes the categorised workbook (both pools, the excluded rows, the 91-table veracity trail, the finding register, the exact values behind every figure, and a study-level meta-analysis), flat CSVs of each pool, a full data dictionary, and a machine-readable citation. Source publications are catalogued with checksums in the accompanying software record but are not redistributed (publisher copyright). This is the dataset of record. The analysis code, the interactive exploration tool and the full reasoning history are archived as a separate software record (concept DOI 10.5281/zenodo.21510123); the two records cross-reference each other.
