Exposure to a large dose in a short period of time is called what?

• A. Chronic
• B. Episodic
• C. Acute
• D. Subacute

Answer: (C)

The term for exposure to a large dose in a short period is acute exposure. In toxicology and environmental health, duration and dose define exposure categories: acute means a high dose delivered quickly, leading to immediate or short-term health effects (often within minutes to hours). This differs from chronic exposure, which involves lower doses over a long time (months to years) and can cause long-term effects. Subacute describes a timeframe longer than an instantaneous exposure but shorter than chronic, typically days to weeks. Episodic exposure suggests irregular, intermittent exposure and isn’t tied to a single high-dose short-term scenario as cleanly as acute. So the best answer is acute.
