My father worked at Union Carbide separating radioactive uranium from non radioactive uranium. What is not widely known is non radioactive uranium is for sale and you can buy it. I had a piece to play with growing up. It makes a nice lighter flint. There is a new semiconductor uranium ditelluride being considered for quantum computers. As you know there is not much difference between an LED and a computer circuit. They will try to make this substance emit light. Newfound superconductor material could be the 'silicon of quantum computers'
