Radium Gilbert
The ''Radium Gilbert'' was a tugboat built for transporting supplies to, and ore from, the radium and uranium mines in Canada's Northwest Territories. Like the other tugs in the Radium Line she was steel-hulled. She was named after Gilbert Labine, the prospector who discovered radioactive ore where Port Radium was built. She was built in Vancouver, in 1946 disassembled, so she could be shipped by rail to Waterways, Alberta. Like all vessels assembled in Waterways that operated on the Mackenzie River, and its tributaries, after she was reassembled she first proceeded downstream to Lake Athabasca, and down the Slave River, to the portage at Fort Smith, Northwest Territories, Fort Smith. Large tractors towed even large cargo overland around large rapids there. The ''Radium Gilbert'' spent her operational life 1946 to 1980 on Great Bear Lake. She ran aground near Deline, the small community at the outlet for Great Bear Lake. Her wreck remained radioactive decades after she was ...

Radium Gilbert Moored In Port Radium, In 1947
Radium is a chemical element; it has 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 1,600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. For this property, it was widely used in self-luminous paints following its discovery. Of the radioactive elements that occur in quantity, radium is considered particularly toxic, and it is carcinogenic due to the radioactivity of both it and its immediate decay product radon as well as its tendency to accumulate in the bones. Radium, in the form of radium chloride, was discovered by Marie an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Bear Lake
Great Bear Lake (; ) in the boreal forest of Canada is the largest List of lakes of Canada, lake entirely in Canada (Lake Superior and Lake Huron are larger but straddle the Canada–United States border, Canada–US border), the fourth-largest in North America, and the List of lakes by area, eighth-largest in the world. The lake is in the Northwest Territories, on the Arctic Circle between 65th parallel north, 65 and 67th parallel north, 67 degrees of northern latitude and between 118th meridian west, 118 and 123rd meridian west, 123 degrees western longitude, Height above mean sea level, above sea level. The name originated from the Chipewyan language, Chipewyan word , meaning "grizzly bear-water people". The Sahtu, a Dene people, are named after the lake. Grizzly Bear Mountain, or ''Sahoyue'', on the shore of the lake also comes from Chipewyan, meaning "bear-large hill".Johnson, LThe Great Bear Lake: Its Place in History.

Boats Of The Radium Line
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats (such as whaleboats) were intended for offshore use. In modern naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure craft used in recreational boating include ski boats, pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence. Lighters are used to move cargo to and from large ships un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Transport In The Northwest Territories
Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy or organic micronutrients. Its chemical formula, , indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. In liquid form, is also called "water" at standard temperature and pressure. Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice ...

Tugboats Of Canada
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbor, harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing t ...

University Of Alberta
The University of Alberta (also known as U of A or UAlberta, ) is a public research university located in Edmonton, Alberta, Canada. It was founded in 1908 by Alexander Cameron Rutherford, the first premier of Alberta, and Henry Marshall Tory, the university's first president. It was enabled through the ''Post-secondary Learning Act.'' The university is considered a "comprehensive academic and research university" (CARU), which means that it offers a range of academic and professional programs that generally lead to undergraduate and graduate level credentials.
