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.

The Japanese environment ministry had released an estimate last month that over 960 square miles, or 2,400 square kilometers, of land would have to be decontaminated to achieve an annual radiation exposure limit of five millisieverts. The government estimates this would cost more than 1 trillion pounds, or about 13 billion dollars.
Tokyo, June 28 (ANI): A British researcher has said that although concerns have been raised after it was revealed that over three millisieverts of radiation has been measured in the urine of 15 residents living near the Fukushima Daiichi Nuclear Power Plant, this by itself 'shouldn't pose too much of a hazard'.
