R1 (nuclear Reactor)
R1 was the first nuclear reactor of Sweden. It was a research reactor located at the KTH Royal Institute of Technology campus at Valhallavägen in central Stockholm, in the rock beneath the current-day Q buildings. The reactor was active from July 13, 1954 to June 6, 1970. The reactor was dismantled, and there is nothing left of it today; the reactor hall however still exists. History As World War II came to a close, the Swedish government in 1950 formed a group of physicists and engineers to study and learn more about the basics – reactor physics, radiation, materials, etc. – but also to produce medical isotopes. The capacity of the reactor was originally 300 Watt, kW but was later increased to 1 MW. ''R1'' was housed in a large hall reminiscent of a cathedral giving it the nickname the “Cathedral of Science and Technology”. Rolf Sievert served as the head of the radiation department at KTH Royal Institute of Technology and gave the approval to run the reactor. ''R1'' was ...

1970 Disestablishments
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...

Rolf Sievert
Rolf Maximilian Sievert (; 6 May 1896 – 3 October 1966) was a Swedish medical physicist whose major contribution was in the study of the biological effects of ionizing radiation. Sievert was born in Stockholm, Sweden. His parents were Max Sievert and Sofia Carolina Sievert, née Panchéen.Sekiya, M., Yamasaki, M.,Rolf Maximilian Sievert (1896–1966): father of radiation protection, ''Radiological Physics and Technology'', 9, 1–5 (2016). Retrieved 2 July 2021. In 1881, Max Sievert founded the Max Sievert Company in Stockholm. He served as head of the physics laboratory at Sweden's Radiumhemmet from 1924 to 1937, after which he was appointed 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. He was a foun ...
