Which of the following is NOT listed as an exposure route?

Explanation:
In radiation safety, exposure routes describe how radioactive material can enter the body to cause internal dose. The routes typically considered are inhalation, ingestion, and injection. Dermal contact is not usually listed as an exposure route because the skin acts as a barrier and most internal dose comes from material entering the body via the lungs, digestive tract, or through a wound, rather than through normal skin contact. Contamination on the skin is still a concern and should be decontaminated to prevent transfer, but it isn’t counted as an internal exposure route. So, the one not listed as an exposure route is dermal contact.
