How Much Astatine Is Present in a Uranium Ore Rock?

Reader review:

Your astatine article is very, very nice. You have written something which can entertain a wide audience dynamically, i.e. giving hope to the nave and refreshment for the learned. When for a moment my patience failed to attend at the adult level, there would soon follow something a curious sixth-grader could appreciate. ... I hope this is the start of a series; it deserves many readers. -- Richard D.
