Radioactive isotopes in fluorescent starters

Postby HIDLad001 » Fri Nov 11, 2022 2:20 pm

Among my haul of lighting things yesterday was a GE 13w PL-C lamp with an inbuilt starter. It says on the package
Starter bottle in lamp contains Ti^3H
Could anybody help me identify what isotope this is? My best guess is Tritium.
I am based in the USA, but I come here to look at and talk about British and European lamps.

Check me out on Gallery Of Lights and Lighting-Gallery!

Hello,
It sounds like Tritium to me.

For various british starters I know, that the inside of the aluminium can was painted with radium point as a radiation source. Other like the german osram and dutch phi's starters had an opening to allow light to ender as radiation source.
From Germany. Open for any trades. Especially interested in british lighting. Please ask questions!
