Cesium Element | Cesium Atomic Data And Effects of Cesium
Cesium is a rare metallic chemical element used in an assortment of industries. It also has a wide range of isotopes, many of which are radioactive. Since it is highly reactive , the element is not usually found in pure form in nature; Most of the world’s supply comes from minerals and nuclear fission. Consumers typically do not interact directly with cesium or its isotopes, although they may own products that contain it as an ingredient.
In appearance, calcium is soft and silvery white. It has the unusual property of being a liquid at room temperature. The element is also highly reactive, highly alkaline and very electronegative.
Cesium elements can react violently with water, ice or moist air. It is identified with the symbol Cs on the periodic table of the elements, and has an atomic number of 55. The high reactivity of this element means that it appears in many compounds, some of which are toxic.
Discovery Of Cesium
The discovery of the cesium element in 1860 is attributed to Gustav Kirkoff and Robert Buesen. Using a spectrometer from Durkheim, Germany, to analyze mineral waters, two people noticed the existence of a previously unknown element that emitted a distinctive blue line on the spectrum.
Men named the element after the Latin cassius, meaning “gray grey.” By 1882, another chemist had managed to isolate the metal cesium. Writers in British English may be more familiar with the element in the form of cesium.

Effects of Cesium on Health
Humans can be exposed to cesium by breathing, drinking, or eating it. In the air, cesium levels are generally low, but some level of radioactive cesium element has been detected in surface water and in many types of food.
The amount of cesium in food and drink mainly depends on the emission of radioactive cesium through nuclear power plants due to accidents. These accidents have not occurred since the Chernobyl disaster of 1986. People working in the nuclear industry can be exposed to high levels of cesium, but there are a number of preventive measures that can be taken to prevent this.
People are very unlikely to feel the health effects that can be linked to the cesium element itself. When exposed to radioactive cesium, which is highly unlikely, a person may have cell damage from radiation from cesium particles. Because of this, effects such as nausea, vomiting, diarrhea and bleeding can occur. When exposure is prolonged it can result in unconsciousness, followed by coma or death. How severe the effects are depends on the individual’s stamina, duration of exposure and the concentration to which the individual is exposed.
Environmental Effects of Cesium
Cesium element occurs naturally in the environment primarily from erosion of rocks and minerals. It is also released into the air, water and land after the extraction and grinding of minerals. Radioactive isotopes of cesium can be released from nuclear power plants and into the air during nuclear accidents and nuclear weapons testing.
The concentration of radioactive isotopes can be reduced to concentrations only with radioactive decay. Non-radioactive cesium can either be destroyed upon entering the environment or it can react with other compounds to form very specific molecules. Both radioactive and stable cesium chemically behave in the same way as animals within the body of humans.
Cesium in the air can travel long distances before settling on land. Most cesium compounds are very soluble in water. However, cesium in the soil moves into groundwater. It remains firmly bound to soil particles within the upper soil layers and is consequently not readily available for uptake through plant roots. Radioactive cesium elements can fall on the leaves and enter the growing plants.
Animals exposed to very high doses of cesium show behavioral changes, such as increased and decreased activity.
In industry, Cesium element atomic clocks, photoelectric cells, and nuclear medicine. Some radioactive isotopes appear to be highly useful in cancer treatment.
The element is also used as a catalyst to create some desired chemical reactions, and is used in various fields of scientific research. Compounds are available at very reasonable prices; In its purest form, it can be quite expensive.
Radioactive cesium isotopes can enter the environment through the explosion of nuclear equipment and through improperly handled waste. These isotopes can cross into drinking water and rivers, potentially causing human health effects ranging from convulsions to death, depending on the exposure.
Fortunately, cesium poisoning appears to be quite rare, as high concentration is required to reach toxicity. However, due to its reactivity and toxicity, care must be exercised when handling the element and its isotopes.
