Cesium (from wikipedia)
"It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature."
- gus_massa 4y agoMetallic Cesium reacts too fast with Oxygen. They are using a salt with Cesium. For obvious reasons it's easier to find videos with metallic Sodium instead of metallic Cesium. Both are chemically similar and react with Oxygen very fast and must be stored protected from Oxygen, and water, and many other things. For example https://www.youtube.com/watch?v=u20yy-CycGU https://www.youtube.com/watch?v=u20yy-CycGU https://www.youtube.com/watch?v=dmcfsEEogxs https://www.youtube.com/watch?v=dmcfsEEogxs It's very difficult to store metallic Sodium, but it's quite easy to store Sodium salts. The relevant paragraph in Wikipedia is > Also the higher specific activity caesium sources tend to be made from very soluble caesium chloride (CsCl), as a result if a radiography source was damaged it would increase the spread of the contamination. It is possible to make water insoluble caesium sources (with various ferrocyanide compounds such as Ni 2Fe(CN) 6, and ammonium ferric hexacyano ferrate (AFCF), Giese salt, ferric ammonium ferrocyanide) but their specific activity will be much lower.
