    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".

    I have a similar clock. Here are the results from
    a scan a decade ago:

    "I checked your clock today. The face surface reading
    is 15,000 cpm (Background = 50 cpm), and 58 microroentgens/hour
    (Background = 8 microroentgens/hour)...."
