=Health and Cobalt.= Cobalt is a radioactive metal that is used in radiotherapy.

Mammals require small amounts of cobalt, which is the basis of vitamin B. The metal has the unfortunate habit of producing a fine dust, causing problems with radiation protection. Cobalt improves the health of grazing animals. Cobalt is an important source of gamma rays and is used to treat some forms of cancer. Cobalt is used to treat anemia with pregnant women, because it stimulates the production of red blood cells. Too high concentrations of cobalt may damage human health. When we breathe in too high concentrations of cobalt through air we experience lung effects, such as asthma and pneumonia. Health effects that are a result of the uptake of high concentrations of cobalt are: - Vomiting and nausea - Vision problems - Heart problems - Thyroid damage
