Which term describes small amounts of radiation absorbed repeatedly over a long period, with effects that may appear years later?

Which term describes small amounts of radiation absorbed repeatedly over a long period, with effects that may appear years later?

• A. Chronic Radiation Exposure
• B. Acute Radiation Exposure
• C. Calcium Tungstate
• D. Maximum Permissible Dose (MPD)

Answer: (A)

Understanding how radiation exposure is described helps distinguish patterns over time. When small amounts of radiation are absorbed repeatedly over a long period, the total dose accumulates, and the resulting health effects may not become apparent until many years later. This pattern—repeated, low-dose exposure with delayed outcomes—fits chronic radiation exposure. In contrast, an acute exposure involves a high dose over a short time with immediate or near-term effects; calcium tungstate is a material used in older x-ray screens, and a maximum permissible dose is a safety limit, not a description of exposure. So the described scenario aligns with chronic radiation exposure.
