Professor Rolf Maximilian Sievert (6 May1896 - 3 October1966) was a medical physicist whose major contribution was in the study of the biological effects of radiation.
Professor Sievert was born in Stockholm, Sweden and spent the majority of his career there.
He invented a number of instruments for measuring radiation doses, the most widely known being the Sievert chamber.
In 1979, at the Conférence Générale des Poids et Mesures (General Conference on Weights and Measures or CGPM), the unit for ionizing radiation dose equivalent was named after him and given the name sievert (Sv).

The sievert (symbol: Sv) is the SI derived unit of dose equivalent.
It attempts to reflect the biological effects of radiation as opposed to the physical aspects, which are characterised by the absorbed dose, measured in grays.
It is named after RolfSievert, a Swedish medical physicist famous for work on radiation dosage measurement and research into the biological effects of radiation.
