Promethium (Pm) is a synthetic rare-earth metal produced artificially through nuclear fission, with no stable isotopes occurring naturally. It has been explored primarily in research and specialized nuclear applications, particularly in self-luminous devices and radioisotope power sources, though its radioactive nature and limited availability have restricted widespread industrial adoption compared to other rare-earth elements.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
