Granite rocks exhibit mysterious black spheres, known as radiohalos. The only reasonable explanation for their origin is a recent, worldwide Flood. Indeed, the unique conditions required to form such spheres show us that radioactive decay—and granite formation—was extremely rapid in the past.

Part two of this series explained why old-earth geologists are baffled by evidence of radioactive damage from polonium in certain kinds of granite crystals, called biotite. These damaged areas, called radiohalos, look like dark “halos.” To the evolutionist, their existence is a mystery.

Why the mystery? The source of these halos, polonium, is an unstable, radioactive element that does not survive long in nature (only milliseconds, in some cases). It appears only briefly during the decay of another element, uranium. But no uranium source is found at the center of these polonium radiohalos! Where did the polonium come from?

The cataclysmic, worldwide Flood provides the answer. Uranium-238 is found a short distance away from the polonium radiohalos. Hot water seeping through the granite during the Flood could easily explain how products of the uranium’s decay could be transported to the site of the polonium radiohalos.
