• A. Acute Exposure
• B. Dose Rate
• C. Occupational Dose
• D. Chronic Exposure

Answer: (D)

Chronic exposure means being exposed to radiation over an extended period with small doses that accumulate over time. The description—small doses spread out over months or years—fits this pattern perfectly because it emphasizes duration and accumulation rather than one single event. In contrast, acute exposure is a short, single incident involving a relatively high dose, which is not what the scenario describes. Dose rate focuses on how quickly energy is delivered, not how long the exposure lasts, and occupational dose refers to exposure that occurs in a work setting rather than the timing of the exposure itself. So, the prolonged, low-dose nature of the described exposure makes chronic exposure the best fit.
