Which term describes when a large dose of radiation is absorbed in a short period, such as in a nuclear accident?

• A. Acute Radiation Exposure
• B. Chronic Radiation Exposure
• C. Beam Alignment Device
• D. Bitewing

Answer: (A)

This question tests understanding of how radiation exposure is described by timing. A large dose absorbed in a short period is called acute radiation exposure. In a nuclear accident, for example, people can experience a sudden, high-dose exposure, leading to rapid health effects. Chronic radiation exposure refers to smaller doses received over a long time, gradually accumulating rather than all at once. The other terms relate to dental imaging tools or image types, not to how the body is exposed to radiation over time.
