Section 20: Radionuclides

There is no HRS score pathway for radionuclides, but there are special considerations that come into play within each of the four pathways when radioactive substances are present.

Section 19: Soil Exposure - Nearby Population Threat

Learn about soil exposure and nearby population threat, which assesses the relative risk that nearby individuals (residents, students, and day care children) may travel to the site and come into contact with hazardous substances.

Section 16: Air - Likelihood of Release

Learn about the air migration pathway for evaluating HRS scores and the likelihood of hazardous gas and particulate substance release.

Section 11: Surface Water - Likelihood of Release

Learn about the surface water pathway, the most complex pathway for evaluating Hazard Ranking System (HRS) scores.

Section 10: Ground Water - Waste Characteristics & Targets

Learn about the waste characteristics factor category in the ground water pathway, which is made up of two components: the toxicity/mobility of the most hazardous substance associated with the site and the hazardous waste quantity at the site.

Section 9: Ground Water - Likelihood of Release

Learn how EPA evaluates an identified aquifer's likelihood of release factor category for the purpose of scoring the ground water pathway.
