Promethium is a radioactive lanthanide produced synthetically and found only in trace amounts as fission product or made in reactors.
Properties of Promethium | It exhibits typical lanthanide chemistry, is radioactive with no stable isotopes and has limited commercial uses due to scarcity and radioactivity.
Uses of Promethium | Used in research, luminous paint historically and as a beta source for thickness gauges and nuclear batteries in specialized applications.
Isotopes of Promethium | Promethium isotopes e.g., Pm 147 are radioactive and require radiological controls for handling, storage and disposal.
