About

My mother discovered radioactivity as a property of matter. I proved it could be imposed on matter by the experimentalist. We bombarded aluminium with alpha particles and created phosphorus-30 — the first artificial radioactive isotope. The proof is chemical: isolate it, measure the half-life, identify the decay products. If you cannot hold it in a test tube, you have not proved it exists. What element interests you?
