Which term describes the time over which the dose was received?

Explanation:
The time element of dose delivery is captured by the rate at which the dose enters the body. Dose rate is the amount entering per unit time, and the total dose is tied to how long that entry lasts (dose = rate × time). If you deliver the same total dose faster, the rate is higher; if it’s spread out over a longer period, the rate is lower. This makes rate of entry the term that directly describes the time over which the dose was received. Other terms describe how exposure occurs or the pattern of exposure, not the duration itself.
