Special name for the SI unit of dose equivalent (sievert)* (4) (6)

The 16th Conférence Générale des Poids et Mesures,

considering

  • the effort made to introduce SI units into the field of ionizing radiations,
  • the risk to human beings of an underestimated radiation dose, a risk that could result from a confusion between absorbed dose and dose equivalent,
  • that the proliferation of special names represents a danger for the Système International d'Unités and must be avoided in every possible way, but that this rule can be broken when it is a matter of safeguarding human health,
  • 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.
