Referensi

Prometium (uniné /prəˈmiːθiəm/, /proʊˈmiːθiəm/) kuwi sawijining unsur kimia kanthi simbul Pm lan nomer atom 61.

Campuran

Campuran Prometium antara liya awujud:

Chlorida
- PmCl₃
Bromida
- PmBr₃
Oksida
- Pm₂O₃

Pènget

Prometium kudu ditangani kanthi ati-ati banget amarga sipaté kang radioaktif banget. Utamané, prometium bisa mancarké sinar X jroning kahanan beta decay. Umur paroné kurang saka plutonium-239 kanthi faktor watara 1350, lan sipat mawa racun biologiné uga dadi luwih dhuwur. Prometium ora nduwèni peran biologi.
