Promethium is an element with atomic number 61. It has no stable isotopes, the longest lived one has half life 17 years. It can be recovered from spent nuclear fuel in small amounts, but in nature it occurs only in minute amounts associated with uranium, from which it is being formed continually and then decaying, so it never accumulates to any extent. It is one of the lanthanides or 'rare earth' elements, and had never been separated until after nuclear reactors had started to operate, providing a source of it.
