Pleochroic halos produced in granite by concentrated specks of short half-life elements such as polonium suggest a period of rapid nuclear decay of the long half-life parent isotopes during the formation of the rocks and rapid formation of the rocks, both of which speak against the usual ideas of geological deep time and a vast age of the earth. See, Radiohalos: Startling evidence of catastrophic geologic processes, Creation 28(2):46–50, 2006.

G131: Polonium haloes indicate a young earth
http://www.answersincreation.org/argument/G131_creation_science.htm
Response:
1.Polonium forms from the alpha decay of radon, which is one of the decay products of uranium. Since radon is a gas, it can migrate through small cracks in the minerals. The fact that polonium haloes are found only associated with uranium (the parent mineral for producing radon) supports this conclusion, as does the fact that such haloes are commonly found along cracks (Brawley 1992; Wakefield 1998).
2.The locations that Gentry collected some of his samples introduces problems that he has not accounted for in his argument
3.Stromatolites (impressions of living organisms) exists in the rocks intruded by the dikes from which Gentry got his samples. This means there was living organisms present before the dikes, and his haloes, existed, which is contrary to his theory that the haloes come from primordial material (pre-life)

"Polonium Haloes" Refuted A Review of "Radioactive Halos in a Radio-Chronological and Cosmological Perspective" by Robert V. Gentry

Summary/Conclusions
Gentry's polonium halo hypothesis for a young Earth fails, or is inconclusive for, all tests. Gentry's entire thesis is built on a compounded set of assumptions. (jatkuu)
