Exposure Pathways

The way in which people are exposed to radiation or other contaminants. The three basic pathways are inhalation (contaminants are taken into the lungs), ingestion (contaminants are swallowed) and direct (external) exposure (contaminants cause damage from outside the body). https://healthymaterialslab.org/tool-guides/hml-resources
