Data comprise site location, soil chemistry (pH, soil moisture), soil radionuclide activity concentrations (the isotopes measured were: Americium-241, Caesium-137, Plutonium-238, -239 and -240, Strontium-90 (K-40 and U-238 activity concentrations were estimated from stable element data) and soil biological activity (derived from application of bait lamina sticks) at 18 sites in the Chernobyl Exclusion Zone (CEZ), Ukraine in 2016; data for four sites in 2005 are also presented. Estimate absorbed radionuclide dose rates to soil invertebrates and bacteria are also presented. The primary purpose of these data was to enable an evaluation of the potential impact of radiation on soil organisms. The work was carried out by UKCEH, Chernobyl Centre for Nuclear Safety and the University of Salford. Funding for this work was via the TREE project funded by NERC, Environment Agency and Radioactive Waste Management Ltd. under the RATE programme.

Data comprise a catalogue of motion activated digital trap camera images of Eurasian Lynx (Lynx lynx (L., 1758)) obtained from motion-activated digital trap cameras located within the Chornobyl Exclusion Zone, Ukraine (CEZ) over multiple years (2012-2018). Images of Eurasian lynx obtained from the cameras are included as part of the dataset. The data were obtained from three research projects: (1) NatEnvPr - Studies conducted 2012–2018 (2) TREE - Studies conducted 2014–2016 and (3) RED FIRE - Studies conducted 2016–2017 The cameras for all projects were setup with the aim to capture images of medium-large mammals; the studies were not designed to obtain quantitative assessments of abundance and density of Eurasian lynx across the CEZ. No bait was used during any of the studies. Full details about this dataset can be found at https://doi.org/10.5285/c099d04e-72e0-4ee9-ac72-11dc004ec1f6
