really want to layout the monies for something that's going to end of life
on me shortly (few years) afterwards.

I know that handling (Caesium) Cesium-133 is tricky at best. It's a heavy
alkali metal and contact with moisture is right out! 
Other than that it's not terribly difficult to create a safe environment to
work with it.

So there must be something else that's considerably more difficult than
opening the tube, recharging the ampoule, resealing it, pulling an ultra
high vacuum and baking it out.

I've not seen any pictures of a naked CBT, still I'm not too worried about
cracking the tube open if its Pyrex, unless resealing it caused the cesium
beam collimation to be lost.

Are there if any getters to worry about? If so, how would one ablate the
contaminates of the surface?

Anyone care to start a discussion on the merits of restoring a CBT to life?
