A gray (Gy) is the SI derived unit of absorbed dose and specific energy (energy per unit mass). Such energies are usually associated with ionising radiation such as gamma particles or X-rays. It is defined as the absorption of one joule of energy in the form of ionizing radiation by one kilogram of tissue. In the SI basic units, a gray is expressed as m²⋅s^-².
A sievert (Sv) is the SI derived unit of equivalent radiation dose, effective dose, and committed dose. One sievert is the amount of radiation necessary to produce the same effect on living tissue as one gray of high-penetration x-rays. Quantities that are measured in sieverts represent the biological effects of ionizing radiation. 1 sievert is the energy absorbed by one kilogram of biological tissue, which has the same effect as one gray of the absorbed dose of gamma radiation. Therefore the sievert can be expressed in terms of other SI units as 1 Sv = 1 J/kg.
