radiation biology database RES³T RES³T (Rossendorf Expert System for Surface and Sorption Thermodynamics) is a freely accessible online thermodynamic reference database for radionuclide sorption data, providing links to experimental sorption data, surface complexation model parameters, spectroscopic evidence and quantum chemical approaches for contaminant transport modelling. It supports safety assessment of radioactive waste repositories and remediation of contaminated sites by providing critically evaluated data for predicting radionuclide mobility in geological and environmental systems. Access is free but usage must be cited. Located at HZDR. http://www.hzdr.de/res3t Paul Schofield DOI: 10.1016/S0169-7722(02)00129-8
