Which statement correctly describes acute radiation exposure?

• A. It occurs from long-term low dose exposures
• B. It occurs from short-term high dose exposures
• C. It occurs only in natural settings
• D. It does not occur in workers

Answer: (B)

Acute radiation exposure means a large dose delivered in a short period. When a high amount of radiation is absorbed quickly, it can produce immediate health effects, sometimes called acute radiation syndrome, depending on the total dose. This is different from chronic exposure, where smaller doses accumulate over time from ongoing work or environment. So the statement describing short-term high dose exposures is the best fit. The other ideas describe chronic exposure (long-term low doses), or inaccuracies about where exposure occurs (it can happen in workplaces, not only in natural settings).
