Refuted long back. These haloes were not created by Polonium at all. So the entire argument falls splat.There is direct irrefutable evidence from Polonium halos that the rock layers of the Grand Canyon where all formed within a short time, during the worldwide flood.
Robert Gentry has made several startling discoveries about certain granites, certain coalified wood samples, and polonium radio halos which he found in each. These have shown that the earth was formed instantly and that the rock layers of the Colorado Plateau where all formed in about 1 year, the result of the worldwide flood. This is all documented in his book “Creation’s Tiny Mystery”.
The part that shows that the rock layers of the Colorado Plateau where all formed within a short time, the result of the worldwide flood, is documented in chapter 4 of the book. In particular, Gentry has documented that there was a single event that produced these rocks layers, which evolutionist claim took supposedly took about 50 to 200 million years. Each coalified wood samples from each of 3 separate rock layers has a set of secondary polonium 210 halos, some elliptical and some circular. The elliptical ones were at one time circular but were flattened by the weight of the above layers while the lower layer containing the polonium 210 halos was still wet and in a gel like state. The circular ones formed after when those layers were hardened. This was documented in these 3 layers.
Please read that chapter as well as the rest of the book if you can so that you can understand this completely.
You can read of his work with primordial polonium 210, 214, and 218 halos which proves that the earth was created instantly. You can also read about why these granites were not from a cooled molten state. You can read about a falsification test challenge that Gentry has given for both of these. You can read about the polonium 210 halos that prove that the worldwide flood happened. You can read about the ratio of U-238 to Pb-206 that is off by a factor of 10,000 in these samples. You read about the discrimination that and censorship he faced due to the implications of his discoveries. And a lot more.
