The Risk Assessment Information System

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.
