  Medical Radiation Physics - Rolf Sievert   (Site not responding. Last check: 2007-10-21)
Already in 1919 Rolf Sievert took contact with radiologists, physiscians using ionizing radiation in their work, and offered them his co-operation in the atempt to solve the physical problems linked with the usage of radiation for diagnosis and therapy.
For that reason, Sievert started an organization in 1925 which was made resposible for the continous control of dosage levels at all clinics in the country performing radiation treatment.The control programme was extended as time went by, and eventually included control of all work with radiation, medical as well as industrial.
During the 1930s Sievert worked primarily with the biological effects of ionizing radiation, and particularly the effects of the low doses received by radiologists in their daily work, and for comparison, the effects caused by unavoidable natural radiation background that we all are exposed to.

 Sievert
The sievert (symbol: Sv) is the SI derived unit of dose equivalent.
It attempts to reflect the biological effects of radiation as opposed to the physical aspects, which are characterised by the absorbed dose, measured in grays.
It is named after Rolf Sievert, a Swedish medical physicist famous for work on radiation dosage measurement and research into the biological effects of radiation.

 Rolf Maximilian Sievert - Wikipedia, the free encyclopedia
Professor Rolf Maximilian Sievert (6 May 1896 – 3 October 1966) was a medical physicist whose major contribution was in the study of the biological effects of radiation.
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.
In 1979, at the Conférence Générale des Poids et Mesures (General Conference on Weights and Measures or CGPM), the unit for ionizing radiation dose equivalent was named after him and given the name sievert (Sv).

 Radiobiology
The sievert replaces an earlier unit called the rem (and abbreviation for "roentgen equivalent, man") which is equal to 0.01 Sv.
The sievert was named in honor of the Swedish physicist Rolf Maximilian Sievert (1898-1966) who developed the basic techniques for measuring absorbed dose.
The gray and the sievert are each equal to a joule per kilogram, but they are not equal to each other.

Among them, Louis Harold Gray (1905 – 1965), a pupil of Ernest Rutherford, established the basis of radiobiology.
During this time, Rolf Maximilian Sievert (1898 – 1966) initiated one of the first radiation protection laws and founded ICRU and ICRP.
By developing the new science of microdosimetry, Harald R. Rossi (1917 – 2000) dominated the biophysical aspects of radiation biology in the last quarter of the 20th century.

 BBC - h2g2 - The Measurement of Radioactivity
In order to take all of these factors into account, a third unit is used, called the sievert (Sv).
A sievert is a derived unit that attempts to express an equivalence of absorbed dosage taking into account biological harm.
Therefore, when assessing the possible effects on members of the public as a result of a large-scale nuclear materials release where they're likely to inhale or ingest the radionuclides, it becomes necessary to express the long-term health effects, and the unit sievert must be used.

At this time Sweden knew virtually nothing about nuclear physics, as all information about the American bombs and the research around them was kept strictly confidential by the United States.
With the mission to "make something with neutrons", the Swedish team, with scientists like Rolf Maximilian Sievert, set out to research the subject and eventually build a nuclear reactor for testing.
After a few years of basic research, they started building a 300 kW (later expanded to 1 MW) reactor, named "Reaktor 1", R1 for short, in a reactor hall 25 meters under the surface right underneath KTH.
