End promo Chris Smith Hello, this week's element sees us immersed in a murder mystery - Henry Nicholls: Henry Nicholls During World War I, Agatha Christie worked in a hospital and then a pharmacy, an experience that could explain the presence of poisons in many of her plots.

High fever, I suppose. Brian Clegg When it comes to practical uses, this silvery substance is an excellent neutron emitter. Chris Smith That's the story of Californium, which apart from its use potentially as a nuclear weapon is also useful for finding gold and striking oil.

It alloys well with other metals to form materials that feature desirable properties, such as low coefficients of friction and acid resistance. Thallium alloys are used in bearings, contact points and solders, and an alloy of thallium and mercury is used in switches and seals designed for low-temperature applications in the polar regions and in space.

Thallium compounds are used in glass lenses for digital cameras, prisms, windows for infrared detection equipment, and in repeaters used in fiber-optic networks. In recent years, thallium compounds have also been used in the development of high-temperature superconductive films, tapes and wires for magnetic energy storage, imaging and propulsion applications.

Thallium is used as a dopant to increase the performance of thermoelectric materials that convert heat to electricity, and thallium isotopes are used in cardiovascular imaging.

Exposure to minute amounts of thallium can be extremely harmful for living organisms. Ingestion of as little as milligrams of thallium is enough to kill a human being. Consequently, disposal of thallium-bearing wastes is controlled by federal, state and local regulations, and storage and transportation of thallium compounds are federally regulated. The leading sources of thallium released into the environment are coal-burning power plants and smelters of copper, lead and zinc ores.

Emergency Management. Survey Manual. Thallium, a soft, bluish-gray, malleable heavy metal, was discovered by Sir William Crookes in while he was making spectroscopic determinations for tellurium on residues from a sulfuric acid plant. Although the metal is reasonably abundant in the Earth's crust at a concentration estimated to be about 0. The major source of commercial thallium is the trace amounts found in copper, lead, zinc, and other sulfide ores.

Thallium is used in photoresistors, infrared optical equipment, low melting glasses and several other applications. However, the use of the product has been prohibited since in the United States. Thallium salts have also been used in the treatment of skin diseases, but the high rate of toxicity compared to the therapeutic benefits limited its medicinal applications.
