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 Texas Commission on Environmental Quality (TCEQ) benchmarks.

Please consult the radionuclide section in the user's guide for more details about the benchmarks, usage of this tool, and guidance on ecological risk assessments.
