That's handy. But do the trash collectors take spent Uranium?

 For years,  they picked up radium-226, which was used on watches  for
radioluminescence
 I miss those radium dials....radioluminescence was a nice feature, but
Radium Girls 'contracted radiation poisoning from painting radium
dials'
 "After being told that the paint was harmless, the women in each
facility ingested deadly amounts of radium after being instructed to
"point" their brushes on their lips in order to give them a fine
tip.[1] The women were instructed to point their brushes in this way
because using rags or a water rinse caused them to use more time and
material, as the paint was made from powdered radium, zinc sulfide (a
phosphor), gum arabic, and water. "

I've read about the girls who painted the radioactive glow paint on clocks, what a horrible way to go.  I had a 40's baby ben alarm clock disassembled at the antique mall where I work, on a day when two Kent State college girls were in.  They had with them a borrowed geiger counter, and when I gave one of them the clock face to test, her eyes got wide at the reading.  She told me "I wouldn't be touching that if I were you".
