Ecological Benchmark Tool for Radionuclides

Screening ecological benchmarks are used to identify concentrations in environmental media that are at or below thresholds for effects to ecological receptors. This tool presents benchmarks for radionuclides from two sources: Los Alamos National Laboratory ECORISK Database – Release 4.3 and the U.S. EPA Region 6 recommendation of using the Texas Commission on Environmental Quality (TCEQ) benchmarks.
