- They don't, but not because of Promethium.
-
- Promethium is used to make the bulbs' arc start more easily.

- Beryllium[sp?] was once used as part of the flourescent powder. This practice
- was stopped when we realized how dangerous it was and when we found
- substitutes. Beryllium salts cause some sort of permanent lung damage. They
- haven't used Beryllium in flourescents for decades.

- I have a yellowed sci fi anthology in which the hero saved the colony by
- telling them how the previous colonists on their Beryllium-rich planet died.
- It seemed that in the twentieth century all uses of Beryllium were phased out
- because it was so toxic, and the fact that it was toxic was not common
- knowledge in the 22nd century, apparently even among scientists whose job it
- was to evaluate the habitibility of biospheres.
-
- Not plausible; surely the biosphere evaluators' tables will have the toxicity
- of Beryllium listed as no better than "unknown". Still, a cute yarn, at least
- to my then-teenage mind. The hero was from the Mneomnic Service; his job was
- to know a zillion isolated facts.
