This page documents an OPTIMADE Unit Definition. See https://schemas.optimade.org/ for more information.

ID: https://schemas.optimade.org/defs/v1.2/units/si/general/sievert
Definition name: sievert

Unit name: sievert
Latin symbol: Sv
Display symbol: Sv

Description: A unit for equivalent dose of ionizing radiation equal to m²·s⁻² using the current, or one of the historical, definitions of the SI units.

"The 16th Conférence Générale des Poids et Mesures, [...] adopts the special name sievert, symbol Sv, for the SI unit of dose equivalent in the field of radioprotection. The sievert is equal to the joule per kilogram." [16th CGPM meeting (1979), resolution 5]

The sievert was defined at the 16th CGPM meeting in 1979 and implicitly redefined via the redefinition of the meter at the 17th CGPM Meeting in 1983, resolution 1.

This is a generalized definition taken to reference the current, or one of the historical, SI unit definitions. This definition is intended for situations when it is not possible to be more precise, e.g., in contexts where data have been collected that uses different historical SI definitions.
