What is the value of 1 Sv in terms of absorbed dose?

The correct value for 1 sievert (Sv) in terms of absorbed dose is 1 Gy, which is equal to 1 joule per kilogram (1 J/kg). The sievert is a derived unit that measures the biological effect of ionizing radiation, taking into account the type of radiation and its impact on human tissues.

The gray (Gy) is the unit for absorbed dose, defined as the amount of radiation energy absorbed per unit mass of tissue, specifically 1 joule of energy absorbed per kilogram of matter. Therefore, since 1 Sv is directly related to the biological effect of absorbed radiation and considers the dose in gray, it is equivalent to 1 Gy in the context of measuring the absorbed dose.

Understanding this relationship is crucial because it highlights how different units are applied in radiation physics to express energy absorption and its potential biological effects.
