The term dose rate refers to the amount of radiation energy absorbed by a person over a specific time period, typically measured in grays per hour (Gy/h) or sieverts per hour (Sv/h). Understanding dose rate is crucial in radiation protection and health physics because it indicates the potential impact of radiation exposure on human health. It helps assess the risk associated with different radiation sources and inform safety protocols.

When discussing the amount of radioactive material present or the rate at which radiation is emitted, these concepts are more related to source strength and radioactivity rather than the direct impact of that radiation on a human body. The distance at which radiation can be felt does not correctly capture the precise measurement of radiation exposure as dose rate does. Therefore, the correct understanding of dose rate is fundamental for evaluating radiation safety and its biological effects.
