Targets

Radionuclides have different benchmarks than chemical substances. These benchmarks have already been determined for you and are found in SCDM.

For the soil exposure pathway, gamma radiation that meets observed release criteria is considered to be Level I concentrations.

If both radionuclides and chemical substances meet observed release criteria at a sampling point and no single substance meets or exceeds a benchmark, you may use the I index (cancer risk) based on both types of substances. The J index is not used for radionuclides.
