sievert

 [se´vert]
the SI unit of radiation absorbed dose equivalent, defined as that producing the same biologic effect in a specified tissue as 1 gray of high-energy x-rays; 1 sievert equals 100 rem.

sie·vert (Sv),

(sē'vĕrt),
The SI unit of ionizing radiation effective dose, equal to the absorbed dose in gray, weighted for both the quality of radiation in question and the tissue response to that radiation. The unit is the joule per kilogram and 1 Sv = 100 rem.
See also: effective dose, equivalent dose.
[R. M. Sievert, Swedish physicist, 1896-1966]

sievert (Sv)

[sē′vərt]
Etymology: R.M. Sievert, twentieth-century Swedish physicist
a measure of radiation dose. The sievert has the same units as the gray and is equal to the absorbed dose times the quality factor, which compares the health consequences of that type of radiation with those of x-rays. The rem bears the same relationship to the rad as the sievert does to the gray.

sievert

Sv Radiation physics The SI unit of biologically effective dose–equivalent dose of ionizing radiation that produces the same biological effect–of ionizing radiaction–dose equivalence; 1.0 Sv = 1.0 joule/kilogram or 100 rem. See Gray, Rad; Roentgen.
