Sievert (symbol: Sv) is the International System of Units (SI) SI derived unit of dose equivalent radiation. It attempts to quantitatively evaluate the biological effects of ionizing radiation as opposed to the physical aspects, which are characterised by the absorbed dose, measured in gray.

It is named after Rolf Maximilian Sievert, a Swedish medical physicist renowned for work on radiation dosage measurement and research into the biological effects of radiation.

SI multiples and conversions Frequently used SI multiples are the millisievert (1 mSv = 0.001 Sv) and microsievert (1 μSv = 0.000001 Sv).

An older unit for the equivalent dose, is the rem, still often used in the United States. One sievert is equal to 100 rem:

• 1 rem = 0.01 Sv = 10 mSv
• 1 mrem = 0.01 mSv = 10 μSv
• 1 Sv = 100 rem
• 1 mSv = 100 mrem = 0.1 rem
• 1 μSv = 0.1 mrem

The conventional units for its time derivative is mSv/h.
