Index Caesium-137

Caesium-137 (Cs-137), cesium-137, or radiocaesium, is a radioactive isotope of caesium which is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. [1]

Ukrainian Soviet Socialist Republic

The Ukrainian Soviet Socialist Republic (Ukrainian SSR or UkrSSR or UkSSR; Украї́нська Радя́нська Соціалісти́чна Респу́бліка, Украї́нська РСР, УРСР; Украи́нская Сове́тская Социалисти́ческая Респу́блика, Украи́нская ССР, УССР; see "Name" section below), also known as the Soviet Ukraine, was one of the constituent republics of the Soviet Union from the Union's inception in 1922 to its breakup in 1991. The republic was governed by the Communist Party of Ukraine as a unitary one-party socialist soviet republic. The Ukrainian SSR was a founding member of the United Nations, although it was legally represented by the All-Union state in its affairs with countries outside of the Soviet Union. Upon the Soviet Union's dissolution and perestroika, the Ukrainian SSR was transformed into the modern nation-state and renamed itself to Ukraine. Throughout its 72-year history, the republic's borders changed many times, with a significant portion of what is now Western Ukraine being annexed by Soviet forces in 1939 from the Republic of Poland, and the addition of Zakarpattia in 1946. From the start, the eastern city of Kharkiv served as the republic's capital. However, in 1934, the seat of government was subsequently moved to the city of Kiev, Ukraine's historic capital. Kiev remained the capital for the rest of the Ukrainian SSR's existence, and remained the capital of independent Ukraine after the breakup of the Soviet Union. Geographically, the Ukrainian SSR was situated in Eastern Europe to the north of the Black Sea, bordered by the Soviet republics of Moldavia, Byelorussia, and the Russian SFSR. The Ukrainian SSR's border with Czechoslovakia formed the Soviet Union's western-most border point. According to the Soviet Census of 1989 the republic had a population of 51,706,746 inhabitants, which fell sharply after the breakup of the Soviet Union. For most of its existence, it ranked second only to the Russian SFSR in population, economic and political power.

University of Tromsø

The University of Tromsø - The Arctic University of Norway (Universitetet i Tromsø – Norges arktiske universitet; is the world's northernmost university. Located in the city of Tromsø, Norway, it was established in 1968, and opened in 1972. It is one of eight universities in Norway. The University of Tromsø is the largest research and educational institution in northern Norway. The University's location makes it a natural venue for the development of studies of the region's natural environment, culture, and society. The main focus of the University's activities is on the Auroral light research, Space science, Fishery science, Biotechnology, Linguistics, Multicultural societies, Saami culture, Telemedicine, epidemiology and a wide spectrum of Arctic research projects. The close vicinity of the Norwegian Polar Institute, the Norwegian Institute of Marine Research and the Polar Environmental Centre gives Tromsø added weight and importance as an international centre for Arctic research. Research activities, however, are not limited to Arctic studies. The University researchers work within a broad range of subjects and are recognised both nationally and internationally. On 1 January 2009, the University of Tromsø merged with Tromsø University College. On 1 August 2013, the university merged with Finnmark University College to form Universitetet i Tromsø – Norges arktiske universitet (The University of Tromsø – The Arctic University of Norway), thereby adding campuses in Alta, Hammerfest and Kirkenes. On 1 January 2016, Narvik University College and Harstad University College merged with UiT - The Arctic University of Norway. As of January 2016 the university now has six campus locations in northern Norway, the main campus being Tromsø.
