* Maybe that's why they've been illegal to manufacture in the US for ~50  
years!! "Glow-in-the-Dark" devices now contain no radioactive materials, just  
very slow phosphors that absorb ambient light.

The biggest risk of  operating a unshielded tube is the extreme high 
voltage present at the  terminals. This can kill!

Like anything else, individual tolerances pay  a big factor with 
radiation and children are at a higher risk for harm  than an adult.
 
 
* A lethal dose is defined as that level at which 50% of those exposed  die 
and 50% still survive! And a few will survive at 10 times that level. They  are 
the ones who will write the anecdotes about how safe it is. 

So,  collect X ray tubes, sure, operate them, absolutely not, unless 
you  understand the risks, especially at higher voltages and exposed  tubes.
Understand radiation exposure is cumulative, the more you play,  the 
more you pay! Implosion of the tube or shock hazards are the 2 biggest  
dangers!
 
 
* All radiation exposure is a form of "Dead-man's Lottery". How many  tickets 
are YOU comfortable buying each year?
