I am going to try to convince one of my customers to let me take 4 CRT's off of their hands rather than them dispose of them. I am going to play the "there are special procedures to dispose of these" card. What is inside the tubes that requires special handling when getting rid of a CRT?
Thanks
Dan

The getter is beryllium. Definitely that's a hazardous material.

The cathode contains Barium or Thorium, depending on type, and the filament is tungsten.
