sie·vert (s  v rt)n. Abbr. Sv A unit of ionizing radiation absorbed dose equivalent in the International System of Units, obtained as a product of the absorbed dose measure in grays and a dimensionless factor, stipulated by the International Commission on Radiological Protection, and indicating the biological effectiveness of the radiation. |
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 [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.
sievert (Sv) (sē´vurt),
n unit used for measuring the combined effects of various types of radiation, its quality and distribution, plus other relative factors.
Sievert
the SI unit of radiation absorbed dose equivalent, defined as that producing the same biological effect in a specified tissue as 1 gray of high-energy x-rays; symbol Sv. 1 sievert equals 100 rem.
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.
