eksponeeritud

Eksponeeritud is a Estonian adjective formed from the verb eksponeerida, meaning that something has undergone exposure to a stimulus or environment. In scientific and technical contexts it is used to describe samples, materials, or subjects that have been subjected to a defined condition, such as light, radiation, heat, or chemicals. The term signals that the exposure process has occurred and may be relevant to ensuing changes or measurements.

Etymology and usage notes: Eksponeerida is a loanword derived from English expose, adapted into Estonian usage with the common verb-forming suffixes. Eksponeeritud functions as a past participle and can be used attributively or predicatively, e.g., eksponeeritud proovid or proovid on eksponeeritud.

Contexts and applications: The term is common in physics, chemistry, biology, materials science and safety disciplines. It often precedes a noun to specify the condition of the subject, such as eksponeeritud materjal (material that has been exposed) or eksponeeritud proov (exposed sample). It can describe exposure to various stimuli, including UV or other radiation, heat, chemicals, or environmental conditions.

Examples: Proovid olid UV-kiirgusele eksponeeritud 2 tundi. Materjal eksponeeritud soojusele näitas muutusi mehaanilises tugevuses. Isiku töötervishoiu hindamisel võib kirjutada, et inimene on eksponeeritud radiatsioonile.

See also: eksponeerimine (the act of exposing), ekspositsioon or eksponatsioon (exposure in specific contexts). Eksponeeritud is typically used in technical and scientific writing to denote that a defined exposure step has been performed.
