Urgeiriça
Urgeiriça is a village in northern Portugal near the town of Viseu. It is part of the civil parish of Canas de Senhorim, in the municipality of Nelas. Small uranium mines and a processing plant are located at this village. Radium mined during the early years of this site supplied Madame Curie. During World War II, control of the uranium resources was a source of concern for the dueling countries. Many countries have purchased uranium mined and then processed into yellowcake from this site including Iraq Iraq,; ku, عێراق, translit=Êraq officially the Republic of Iraq, '; ku, کۆماری عێراق, translit=Komarî Êraq is a country in Western Asia.

Nelas
Nelas () is a municipality located in the Centro Region of continental Portugal. The population in 2011 was 14,037, in an area of 125.71 km². History Settlement of the territory of Nelas dates back to the settlement by Neolithic and Stone age cultures, between 5000 and 3000 BC. Many of the structures that developed in this period were stone slabs and large rocks, and included megalithic monuments such as the Orca Pramelas, in Canas de Senhorim, and Outeiro Roque, near the village Lapa do Lobo. Roman settlements also intersected this territory, with the construction of roads (such as those still visible in Santar and Vilar Seco). Remnants of Middle Age influences can be since on the gravestone in Pedras da Forca. The municipality of Nelas was created on 9 December 1852, during the politico-administrative reforms following the Liberal Revolution, that rationalized the chaotic local administration, and merged the two older municipalities of Senhorim with Canas de Senhorim.

Portugal
Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population. Portugal is the oldest continuously existing nation state on the Iberian Peninsula and one of the oldest in Europe, its territory having been continuously settled, invaded and fought over since prehistoric times. It was inhabited by pre-Celtic and Celtic peoples who had contact with Phoenicians and Ancient Greek traders, it was ruled by the Ro ...

Viseu
Viseu () is a city and municipality in the Centro Region of Portugal and the capital of the district of the same name, with a population of 100,000 inhabitants, and center of the Viseu Dão Lafões intermunipical community, with 267,633 inhabitants. Settled during the period of the early Iberian Castro culture, the territory of Viseu was populated by a series of cultures including the Romans, Suebs, Visigoths and Moors. During the Roman occupation of Iberia, Viriathus, rebel leader of the Lusitanians, is assumed to have lived for a time in the vicinity. During the Middle Ages, the city often served as seat for Visigothic nobles (such as King Roderic), and is considered one of the probable birthplaces of Afonso Henriques, first King of Portugal. Viseu is a regional economic hub with a strong wine industry and is the seat of international conglomerate Visabeira. The city is also a cultural center, home to the nationally acclaimed Grão Vasco Museum, seat of the Roman Catholic Dio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radium
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found ...

Madame Curie
Marie Salomea Skłodowska–Curie ( , , ; born Maria Salomea Skłodowska, ; 7 November 1867 – 4 July 1934) was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and the only woman to win a Nobel Prize twice, and the only person to win a Nobel Prize in two scientific fields. Her husband, Pierre Curie, was a co-winner of her first Nobel Prize, making them the first-ever married couple to win the Nobel Prize and launching the Curie family legacy of five Nobel Prizes. She was, in 1906, the first woman to become a professor at the University of Paris. She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw's clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her elder sister Bronisława to study in Paris, where she earned her highe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
