Actually Helium is what alpha particles become after they acquire 2 electrons. And alpha particles is what Radon radiates [1]. There’s plenty of Helium being produced every moment on this planet. Some gets trapped underground in pockets of natural gas. There is such a case in Arizona, where the natural gas contains 8.3% Helium [2].
