Cerium is very mildly radioactive, to the point of being non radioactive for most practical purposes. Natural cerium is made up of 88.886% stable material, but 11.114% is made up of 142Ce, which has a half life of 50,000,000,000,000,000 years. Like all other elements, there are radioactive synthetic isotopes of cerium.
