Tritium gas "glow-in-the-dark" keyring holders and high end watches are 
available on eBay. They are Beta emitters and very little radioactivity 
escapes. It is detectable on my counter though.  Here's my key ring holder.
A radium watch dial is also shown which is now 70 years old. The phosphor is 
almost invisible now but the counts are strong.

And the Tesla link? I also have counts on that page for a thoriated tungsten 
rod that I use in my rotary spark gap.
