What is the unit of measurement for radiation dose?

The unit of measurement for radiation dose is represented by the Gray (Gy) for absorbed dose and the Sievert (Sv) for equivalent dose. The Gray quantifies the amount of radiation energy absorbed by a specific mass of tissue, while the Sievert is used to express the biological effects of that radiation, accounting for the type of radiation and its impact on health.

The Gray is defined as one joule of radiation energy absorbed per kilogram of matter, making it a standard unit for measuring the dose of radiation that has significant relevance in radiation therapy and radiology. The Sievert, on the other hand, is particularly important in assessing the risk associated with radiation exposure, as it incorporates factors that account for the biological effectiveness of different types of radiation.

Understanding these units is crucial in the field of radiology, as they inform both the safety protocols for patients and healthcare workers, and guide the assessment of potential radiation-induced health risks. This knowledge helps ensure proper management and administration of radiation in clinical settings.
