Radium fluoride 
Summary
Radium fluoride is an inorganic compound with a chemical formula of RaF2. This salt, like all radium compounds is highly radioactive. It can be coprecipitated with lanthanide fluorides.[2] Radium fluoride has the same crystal form as calcium fluoride (fluorite).[citation needed]

Production edit
Radium fluoride can be produced by the reaction of radium metal and hydrogen fluoride gas:[citation needed]
- Ra + 2 HF → RaF2 + H2
