Loch Lomond Radium Works
Loch Lomond Radium Works was a company founded by John Stewart MacArthur in 1911 as the Radium Works in Halton, Cheshire, England. The company moved to Balloch, West Dunbartonshire, Scotland in 1915. The company produced radium for use in medicine and for radioluminescent paint Luminous paint or luminescent paint is paint that exhibits luminescence. In other words, it gives off visible light through fluorescence, phosphorescence, or radioluminescence.

John Stewart MacArthur
John Stewart MacArthur was a chemist from Glasgow. Born on 9 December 1856, he is credited with the development of the MacArthur-Forrest cyanidation process in 1887, used to extract gold in South Africa. His patent for the process was voided. With the long-lasting legal issues about the cyanidation patents, MacArthur turned to other businesses. First, he investigated vanadium extraction from ore containing significant amounts of radium. From this enterprise he turned to the production of radium. He founded the Radium Works in Halton in 1911. In 1915 he moved it to Balloch, West Dunbartonshire and renamed it as Loch Lomond Radium Works. MacArthur died on 16 March 1920, aged 63.

Halton, Runcorn
Halton, formerly a separate village, is now part of the town of Runcorn, Cheshire, England. The name ''Halton'' has been assumed by the Borough of Halton, which includes Runcorn, Widnes and some outlying parishes. History There is evidence of human occupation in the Stone Age and during the Roman era. The village is recorded in the Domesday Book (1086) in the hundred of Tunendune and towards the end of the 11th century the first castle, which became the seat of the Barons of Halton, was built on the hill. The Tunendune hundred court was absorbed into Bucklow hundred by 1260 so government statistics for Halton over many later centuries are indexed by Bucklow hundred. During the medieval period a deer park measuring lay to the south and the west of the village. At this time Halton had a weekly market and annual fair. The village held a court leet and the castle was used as a prison. During the Civil War the castle was held by the Royalists and twice besieged by Parlia ...

Balloch, West Dunbartonshire
Balloch (; Scots pronunciation: ; Gaelic: ''Am Bealach'') is a village in West Dunbartonshire, Scotland, at the foot of Loch Lomond. Etymology Balloch comes from either the Gaelic word ''baile'' which means village or hamlet, or the Gaelic ''bealach'' meaning "a pass". Using the former derivation, Balloch means "village on the loch", i.e. the nearby Loch Lomond, but this would be Baile Loch. Geography Balloch is at the north end of the Vale of Leven, straddling the River Leven itself. It connects to the larger town of Alexandria and to the smaller village of Jamestown, both of which are located to its south. It also borders the Kilpatrick Hills. To the east of the town lies the major local authority housing scheme in the area known as 'The Haldane' or 'The Mill of Haldane'. Glasgow is located around to the southeast. Balloch lies on the 56th parallel, at about the same latitude as Moscow. Tourism With its accessible location at the southern end of Loch Lomond and just of ...

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, ...

Luminous Paint
Luminous paint or luminescent paint is paint that exhibits luminescence. In other words, it gives off visible light through fluorescence, phosphorescence, or radioluminescence. There are three types of luminous paints: fluorescent paint, phosphorescent paint and radioluminescent paint. Fluorescent paint Fluorescent paints 'glow' when exposed to short-wave ultraviolet (UV) radiation. These UV wavelengths are found in sunlight and many artificial lights, but the paint requires a special black light to view so these glowing-paint applications are called 'black-light effects'. Fluorescent paint is available in a wide range of colors and is used in theatrical lighting and effects, posters, and as entertainment for children. The fluorescent chemicals in fluorescent paint absorb the invisible UV radiation, then emit the energy as longer wavelength visible light of a particular color. Human eyes perceive this light as the unusual 'glow' of fluorescence. The painted surface also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loch Lomond
Loch Lomond (; gd, Loch Laomainn - 'Lake of the Elms'Richens, R. J. (1984) ''Elm'', Cambridge University Press.) is a freshwater Scottish loch which crosses the Highland Boundary Fault, often considered the boundary between the lowlands of Central Scotland and the Highlands. Tom Weir. ''The Scottish Lochs''. pp. 33-43. Published by Constable and Company, 1980. Traditionally forming part of the boundary between the counties of Stirlingshire and Dunbartonshire, Loch Lomond is split between the council areas of Stirling, Argyll and Bute and West Dunbartonshire. Its southern shores are about northwest of the centre of Glasgow, Scotland's largest city. The Loch forms part of the Loch Lomond and The Trossachs National Park which was established in 2002. Loch Lomond is long and between wide, with a surface area of . It is the largest lake in Great Britain by surface area; in the United Kingdom, it is surpassed only by Lough Neagh and Lough Erne in Northern Ireland. In the ...

Vale Of Leven
The Vale of Leven (Scottish Gaelic: ''Magh Leamhna'') is an area of West Dunbartonshire, Scotland, in the valley of the River Leven. Historically, it was part of The Lennox, the name of which derives from the Gaelic term ''Leamhnach'', meaning ''field of the Leven''. ''Leamnha'' is thought to mean elm-water. Geographically the valley of the Vale of Leven runs from Loch Lomond in the north to Dumbarton in the south. However, the term "Vale of Leven" or just "The Vale" is commonly used locally to refer to the urban area towards the north of the valley that consists of a number of communities. These were historically separate villages but have expanded into one conurbation. The largest of these communities is the town of Alexandria, which sits on the west bank of the Leven. Alexandria is connected to the village of Renton to the south and to the village of Balloch in the north. Across the river from Alexandria Is Bonhill which is connected to Jamestown to the north.

Chemical Companies Of The United Kingdom
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...
