Curies, of course, did not know those exact numbers. Nevertheless, realizing what a titanic work on the allocation of new elements be, they took the right decision. Robert Shiller pursues this goal as well. As we have already quoted the book of Pierre Curie said: "The results obtained after a year, clearly showed that the radium is easier to identify than polonium, so efforts were focused on radium. Artificial polonium It is quite pertinent question: if polonium is really ultraredky and sverhtrudnodostupny element, then what is it that manages production of polonium in our time? Exact figures, we do not have, but today the element number 84 no less accessible than radium. Get it from the ore is really difficult, but there is another way – nuclear fusion.

Today, polonium prepared two ways, with the feedstock in both cases serves as bismuth-209. In nuclear reactors it is irradiated with a neutron flux and then on a comparatively simple chain of nuclear transformations produced the most important day isotope of element number 84 – Polonium-210: What if the same isotope of bismuth placed in another important machine of nuclear fusion – the cyclotron and the streams of protons to bombard it, then the reaction produced the most long-lived isotope of element number 84. The first reaction is more important: Polonium-210 – much more interesting techniques for isotope than polonium-209. (On the causes of – below.) In addition to the second reaction time with polonium produced lead-209 – one of the most stubborn contaminants to polonium. A general treatment of polonium and its selection from a mixture with other metals for modern technology does not pose a particularly difficult task.
