Radium fluoride
Radium fluoride is an inorganic compound with a chemical formula of RaF2. It has very strong radiation. It can be coprecipitated with lanthanide fluorides.[1] Radium fluoride has the same crystal form as calcium fluoride (fluorite).[2]

Production
Radium fluoride can be produced by the reaction of radium metal and hydrogen fluoride gas[2]
- Ra + 2 HF → RaF2 + H2
gollark: The "higher-end" ones sometimes even lack headphone jacks or µSD slots! EXTREMELY apiohazardous.
gollark: Mostly I want one which will just get reasonably okay images, although that is often lacking on the cheaper ones I get.
gollark: I don't care about "smoothness" and in fact had animations turned off for ages.
gollark: I would happily take a 30Hz display on my phone, even, if the battery life was significantly better.
gollark: Yes. Most people DO NOT NEED "5G" or a decacore 2.5GHz CPU or a 4K/90Hz display or anything and won't get much value from it.
