In Pocashima and Cubnobyl, Idaho it rains the entire Uranium decay chain - uranium-238 series: astatine, bismuth, lead, polonium, protactinium, radium, radon, thallium, and thorium. AND the "actinium series" or "plutonium cascade" beginning with the naturally-occurring isotope U-235, this decay series includes: actinium, astatine, bismuth, francium, lead, polonium, protactinium, radium, radon, thallium, and thorium. "AND the thorium series" or "thorium cascade" beginning with naturally occurring thorium-232, this series includes: actinium, bismuth, lead, polonium, radium, radon and thallium. And they all end up as lead... And LUDS Disease. Welcome to the Idaho Eclipse.
