Luminous paints

Deuterium is used as a moderator to slow down neutrons. Tritium atoms are also present but in much smaller proportions. Tritium is readily produced in nuclear reactors and is used in the production of the hydrogen (fusion) bomb. It is also used as a radioactive agent in making luminous paints, and as a tracer.

Zinc sulfide (ZnS) is used as a pigment and to make white glass, rubber, and plastics. It is an ingredient in pesticides, luminous paints, and X-ray and television screens. 

Barium sulfide occurs in the form of hlack ash, which is a gray to hlack impure product obtained from high temperature carbonaceous reduction of barite. It is the starting material in the manufacture of most barium compounds including barium chloride and barium carbonate. It is used in luminous paints for dehairing hides as a flame retardant and for generating H2S. 

The primary use of this compound is to produce a number of other bismuth compounds. It also is used in luminous paints and enamels applied on tin to produce bismuth luster and for precipitation of alkaloids. 

Calcium sulfide occurs in nature as the mineral oldhamite. It has several applications. The luminous calcium sulfide is used in phosphors, luminous paints and varnishes. Calcium sulfide also is used as an additive to lubricants and as a flotation agent in ore extraction. 

Copper(l) sulfide is used in luminous paints antifouhng paints in sohd-lubricant mixtures in solar cehs in electrodes and as a catalyst. 

CdSe forms solid solutions with CdS which are used as pigments ranging in color from orange to deep maroon and are called cadmium sulfoselenides. Other uses are in photocells, rectifiers, luminous paints, and as a mby colorant for glass manufacture. CdSe currently sells for 1.50/g as ph osphor-grade (99.999% purity) material. 

Luminous dials, gauges, wrist watches Luminous paint... 

Until the 1960s, radium was a component of the luminous paints used for watch and clock dials, instrument panels in airplanes, military instruments, and compasses (Blaufox 1988). 

Calcium sulfide is used as a depilatory in the tanning industry and in cosmetics and, in a finely divided form, it is employed in luminous paints. Calcium polysulfides (CaS ), such as calcium disulfide (CaS2) and calcium pentasulfide (CaS5), are made by heating sulfur and calcium hydroxide.

When she blew her nose, her handkerchief glowed in the dark. The woman who made this statement in the early 1900s was one of several factory workers who were hired to paint clock and watch dials with luminous paint. 

Bismuth nitrate, Bi(N03)2, is used in the production of some luminous paints. How many grams of pure bismuth are in a 268 g sample of bismuth nitrate ...

Emitted by heavy atoms, such as uranium, radium, radon, and plutonium (to name a few), alpha particles are helium nuclei, making them the most massive kind of radiation. Alpha radiation can cause a great deal of damage to the living cells it encounters, but has such a short range in tissue (only a few microns) that external alpha radiation cannot penetrate the dead cells of the epidermis to irradiate the living cells beneath. If inhaled, swallowed, or introduced into open wounds, however, alpha radiation can be very damaging. In nature, alpha radiation is found in rocks and soils as part of the minerals, in air as radon gas, and dissolved in water as radium, uranium, or radon. Alpha emitters are also found in nuclear power plants, nuclear weapons, some luminous paints (radium may be used for this), smoke detectors, and some consumer products. Objects and patients exposed to alpha radiation may become contaminated, but they do not become radioactive. 

Radium Uraniiuns Separation Luminous paint i Cancer therapy (both decreasing)... 

The name comes from the Latin radius, meaning ray. It was discovered by Marie and Pierre Curie in 1898 when they were studying uranium and other radioactive materials found in pitchblende. There is about 1 g of radium in 7 tons of pitchblende, but it is 3xl05 times more radioactive than uranium. It was isolated as a metallic element in 1911 by Marie Curie and Andre-Louis Debieme (1874-1949). Radium exists in small quantities associated with uranium ores. Radium is phosphorescent, so it has been used to make luminous paint, especially for watch dials, but, because it is highly radioactive, most uses are related to nuclear medicine or the energy industry. Radon gas is produced from radium and is a harmful by-product.
