Flourescent and radioactive are two different things.
Dig, how are you.This is true. Also I know nothing about nuclear physics. And I am not trying to scare anyone. All I know is a TV program I watched where workers made flourescent material for alarm clocks. Around 1940 something they discovered the danger as most employees came down with cancer. The flourescent factory was closed down. He found these flourescent thingys dumped miles away from their factory in a farmers field! I guessed they were flourescent by the color. You don't think this needs further looking into?
Here are my thoughts. If you look closely at the cone sitting on the light, you'll notice that it is being lit up, but is not itself lighting up. Look at the very top of the cone. See how it is still dark. The same thing would happen to say a cone made from solid plastic. The bottom would disperse the light and just a little would reach the top. I am sure that it isn't flouressing. Flouressing would give it a nice evenly lit look, as if the light bulb were actually inside it. (think lightning bugs butt)
I also don't think that these are mass produced. Look at how many variations in size there are. Let me rephrase that a bit, I don't think that there was a large volume of these made. I think that they were made there locally by who knows who and for who knows what reason.
As for the workers licking the brush at the radium plant.... well, what can you say? Hindsight is 20/20 right?
When concentrated, radium glows in the dark. Because of this property, it was once mixed with a paste of zinc sulfide to make a self-luminescent paint for watch, clock, and instrument dials. During the 1930s it was found, however, that exposure to radium posed a serious hazard to health: a number of the workers who routinely used the radium-containing luminescent paint developed anemia and, in some cases, bone cancer. The practice of employing radium in luminescent coatings was halted after the high toxicity of the material was recognized. (Encyclopedia Britannica 1997 guide to the Nobel Prizes)
