The sievert symbol Sv is the International System of Units SI SI derived unit of equivalent dose dose equivalent radiation. It attempts to quantitatively evaluate the biological effects of ionizing radiation as opposed to just the absorbed dose of radiation energy, which is measured in Gray unit gray . It is named after Rolf Maximilian Sievert , a Sweden Swedish medical physicist renowned for work on radiation dosage measurement and research into the biological effects of radiation. Definition The unit gray measures the absorbed dose of radiation D , absorbed by any material. The unit sievert measures the equivalent dose of radiation H , having the same damaging effect as an equal dose of gamma rays. Both the gray, with symbol Gy and the sievert, with symbol Sv are SI derived unit s, defined as a unit of energy joule per unit of mass kilogram 1 Gy 1 Sv 1 joule J kilogram kg SI unit lowercase Rolf Maximilian Sievertsievert Sv Dose equivalent The equivalent dose to a tissue is found by multiplying the absorbed dose, in gray, by a weighting factor W sub R sub . The relation between absorbed dose D and equivalent dose H is thus math H W R cdot D math . The weighting factor sometimes referred to as a quality factor is determined by the radiation type and energy range. ref name icrp103 ... used in the United States.

File Rolf Sievert 1896 1966.jpg thumb 200px Professor Rolf Maximilian Sievert 6 May 1896 &ndash 3 October 1966 was a medical physicist whose major contribution was in the study of the biological effects of Ionizing radiation radiation . Professor Sievert IPA sv si v was born in Stockholm , Sweden . He served as head of the physics laboratory at Sweden s Radiumhemmet from 1924 to 1937, when he became head of the department of radiation physics at the Karolinska Institute . He played a pioneering role in the measurement of doses of radiation especially in its use in the diagnosis and treatment of cancer . In later years, he focused his research on the biological effects of repeated exposure to low doses of radiation. In 1964, he founded the International Radiation Protection Association , serving for a time as its chairman. He also chaired the United Nations Scientific Committee on the Effects of Atomic Radiation . He invented a number of instruments for measuring radiation doses, the most widely known being the Sievert chamber .
