    I have another problem with the Radium in these units – you are playing TSA-roulette if you ever try and put one on a commercial flight, checked luggage or not. Sometimes the agent will listen to reason, but sometimes the howling Geiger counter puts them in an un-responsive mood.


    It’s a pity, really. I’d love to own one.

    I do have one very specific concern, which has not been addressed. Ingestion. Paint is not permanent. It can and will degrade, producing dust. The degradation is neither enhanced nor inhibited by the addition of radium. As the radium infused dust moves about, it will migrate out of your instrument, onto your hands and then into your body. One can argue that the amount is minuscule, yet no level of ingestion is safe.
