Exempel på hur man kan använda SIEVERT i en mening

• The sievert (symbol: Sv) is a unit in the International System of Units (SI) intended to represent the stochastic health risk of ionizing radiation, which is defined as the probability of causing radiation-induced cancer and genetic damage.
• In 1979, at the Conférence Générale des Poids et Mesures (General Conference on Weights and Measures or CGPM), the SI unit for ionizing radiation dose equivalent was named after him and given the name sievert (Sv).
• The sievert is a unit of weighted radiation dose for ionising radiation, which supersedes the older weighted unit the rem (roentgen equivalent man).
• Total recorded doses to individual workers in Chernobyl recovery operations during the period through 1990 ranged from less than 10 millisieverts (less than 1 rem) to more than 1 sievert (100 rems), due primarily to external radiation.
• The article on the sievert summarises the recommendations of the ICRU and ICRP on the use of dose quantities and includes a guide to the effects of ionizing radiation as measured in sieverts, and gives examples of approximate figures of dose uptake in certain situations.
• Directive 80/181/EEC, published in December 1979, which replaced directive 71/354/EEC, explicitly catalogued the gray, becquerel, and sievert for this purpose and required that the curie, rad, rem and roentgen be phased out by 31 December 1985.
• By 2018, the IPK underpinned the definitions of four of the seven SI base units: the kilogram itself, plus the mole, ampere, and candela (whose definitions at the time referenced the gram, newton, and watt respectively) as well as the definitions of every named SI derived unit except the hertz, becquerel, degree Celsius, gray, sievert, farad, ohm, siemens, henry, radian and steradian.
• The following table includes some dosages for comparison purposes, using millisieverts (mSv) (one thousandth of a sievert).
• These are mostly additions to the list of named derived units, and include the mole (symbol mol) for an amount of substance, the pascal (symbol Pa) for pressure, the siemens (symbol S) for electrical conductance, the becquerel (symbol Bq) for "activity referred to a radionuclide", the gray (symbol Gy) for ionising radiation, the sievert (symbol Sv) as the unit of dose equivalent radiation, and the katal (symbol kat) for catalytic activity.
