Physicist Robert Gentry has reported isolated radio halos of plonium-214 in crystalline granite. The half-life of this element is 0.000164 seconds! To record the existence of this element in such short time span, the granite must be in crystalline state instantaneously. What foolishness. Polonium-214 is a decay product of radon, which is produced by the decay of uranium, which is present in granite. In any piece of granite, trace quantities of polonium are being produced all the time. Of course you will find evidence for polonium decays in granite!
Read the study and refute, do not read my bullet and make statements with no sources.
