MIL-li-SEE-vurts

Definition

A standard unit of measurement for ionizing radiation dose that accounts for the biological effect of radiation on human tissue.

Etymology

The term is a compound of the SI prefix 'milli-' (meaning one-thousandth) and 'sievert,' which was named in 1979 in honor of the Swedish medical physicist Rolf Sievert.

In the news

The article uses millisieverts to quantify the extremely low levels of artificial radiation Finns are exposed to compared to their average annual total dose. This unit helps demonstrate that current radiation levels are well within safe, non-harmful limits.
