ActClassExposure

The interaction of entities whereupon a subject entity is brought into proximity to a physical, chemical or biological agent. This includes intended exposure (e.g. administering a drug product) as well as accidental or environmental exposure. (Note: This class deals only with proximity and not the effectiveness of the exposure, i.e. not all exposed will suffer actual harm or benefit.) Examples: Exposure to radiation, drug administration, inhalation of peanut aerosol or viral particles.
