Effect of increasing concentration of cobalt ion irradiation

The rest is absorbed into the blood and then into the tissues throughout the body. Therefore, we do not always know the chemical form of cobalt to which a person may be exposed.

hexaaquacobalt(ii)

However, too high concentrations of cobalt may damage human health. The element has a medium abundance but natural compounds of cobalt are numerous and small amounts of cobalt compounds are found in most rocks, soils, plants, and animals.

Studies in animals have suggested that children may absorb more cobalt from foods and liquids containing cobalt than adults. It may enter air and water, and settle on land from windblown dust, seawater spray, volcanic eruptions, and forest fires and may additionally get into surface water from runoff and leaching when rainwater washes through soil and rock containing cobalt.

cobalt reactions

If cobalt is presence on the skin in can lead to an irritation and rash. This complex was first isolated by Werner as yellow-gold needle-like crystals. Different units are used to measure the rate of emission from a radioactive source, the energy that is absorbed from the source, and the amount of damage the absorbed radiation does.

Cobalt ions

Another oxidation of hexaaquacobalt II ions Rather than relying on oxidation by the air, you can add an oxidizing agent such as hydrogen peroxide. Industrial exposure results mainly from breathing cobalt-containing dust. Small amounts of cobalt may be released into the atmosphere from coal-fired power plants and incinerators, vehicular exhaust, industrial activities relating to the mining and processing of cobaltcontaining ores, and the production and use of cobalt alloys and chemicals. This element belongs to the eighth iron-group. The concentration of cobalt in surface and groundwater in the United States is generally low—between 1 and 10 parts of cobalt in 1 billion parts of water ppb in populated areas; concentration may be hundreds or thousands times higher in areas that are rich in cobalt-containing minerals or in areas near mining or smelting operations. If you are exposed to cobalt, many factors determine whether you'll be harmed. They are also used in artificial hip and knee joints. Newton, David. When a substance is released from a large area, such as an industrial plant, or from a container, such as a drum or bottle, it enters the environment. Effects on the thyroid were found in people exposed to 0.

All isotopes of cobalt behave the same chemically and will therefore have the same chemical behavior in the environment and the same chemical effects on your body.

Levels of cobalt normally found in the environment, however, are not high enough to result in excess amounts of cobalt in food or water.
