exponeringsförhållanden

Could you clarify what the term “exponeringsför…” refers to? The fragment could correspond to several Swedish terms, and I want to ensure I write the correct article. Here are a few plausible interpretations:

- Exponering (exposure) in photography and cinema: the amount of light reaching the sensor or film, and how it is controlled by aperture, shutter speed, and ISO.

- Exponeringsförmåga or exponeringsgränser in occupational health or radiation protection: a person’s or a substance’s potential to be exposed to a hazard, and how exposure is assessed and managed.

- A different concept related to exposure in science or media.

If you confirm the exact term and the intended focus (historical, technical, policy-related, etc.), I will draft a concise, neutral wiki-style article under 300 words.
