Which SI unit is used for measuring absorbed dose?

The SI unit used for measuring absorbed dose is the Gray. This unit quantifies the amount of radiation energy absorbed by a given mass of material, typically measured in joules per kilogram. The Gray is particularly relevant in the fields of radiology and radiation therapy, as it helps assess the effects of ionizing radiation on biological tissues.

The other units mentioned are used for different purposes: Becquerel is the unit for measuring radioactivity, specifically the rate of decay of radioactive material. The Sievert measures the biological effects of radiation on living organisms, taking into account the type of radiation and its impact. Air Kerma refers to the kinetic energy released in air and is typically used in dosimetry to describe exposure to radiation in air rather than absorbed dose in tissues. Understanding these distinctions is crucial in the fields related to ionizing radiation.
