For what it's worth, I also was fascinated to see my toes wiggle in the
Buster Brown shoes as I and the shoe salesman looked at the x-ray image
of my feet in my new shoes. Other than the salesmen getting multiple
x-ray doses, the main problem was that the x-rays were irradiating our
gonads and head as we peered down through the machine to see our feet.
At the time, x-ray exposure was not well collimated, if at all, for any
such irradiation, including dentistry.
i also loved my Gilbert Chemistry set, particularly when I burned the
sulfur! My mother then thru me out of the house!
Finally, the toxicity of U-238 is not due to its alpha and gamma
radioactivity; Its half-life is in the billions of years, as I recall.
The problem with U-238 is its chemical toxicity, which incidentally does
include the alpha emissions as an aspect.
Great discussion - Dick
