Dysprosium-158 Information

Dysprosium is a metallic element with a bright silvery-white lustre. Dysprosium belongs to the lanthanoids. It is relatively stable in air at room temperatures, it will however dissolve in mineral acids, evolving hydrogen. This element is found in from rare-earth minerals. It has 38 isotopes. There are seven natural stable isotopes of dysprosium. Dy-154 being the most stable with a half-life of 3*10^6 years. Dysprosium is used as a neutron absorber in nuclear fission reactions, and in compact disks. It was discovered by Paul Emile Lecoq de Boisbaudran in 1886 in France. Its name Dysprosium comes from the Greek word dysprositos, which means hard to obtain.

Dysprosium uses are limited to the experimental and esoteric.
