Polonium isn't something you mix up in your garage by cooking cold tablets containing pseudo-ephedrine. According to one source only about 100 grams are made worldwide annually - about two-tenths of a pound.
Although it is extremely toxic, a tiny amount of polonium is available for purchase by you, or me, or Vladimir Putin (if he uses a fake US address) from an outfit in New Mexico known as United Nuclear Scientific Supplies, LLC for $69.
