The following question was answered by an expert in the appropriate field:

Where did the word "sievert" originate? Was it named after someone?

The sievert, Sv, was accepted in 1979 as the unit for dose equivalent for ionizing radiation. This unit is a part of the SI-system for units and measures. For information about Rolf Sievert and more on the unit, go to the Karolinska Institutet website.
