Oh no...not the dreaded polonium halos!

SpinyNorman73, Dr. Robert Gentry's is another nucleur physicist, he found polonium radioactive halo's in the granite crystals shows the entire granite basement rock's of the earth were formed instantly, these radioactive halo's shouldn't be within granites crystals, he used an analogy of Alka-Seltzer bubbles in water would disappear quickly unless the water was frozen instantly, these polonium atoms only exists for seconds before they disappear, because they exists as radioactive polonium halo's, within the granites support they were supernaturally created, etc...
A while back, the same sort of garbage appeared in our school newspaper, using polonium halos to prove that the Earth was instantly created. I wrote a reply and I will duplicate it here. (I gathered the information from a couple sources, and I think that Talk Origins was one of them, but honestly, I don't remember where I got all of the information).
When all the evidence is examined rather than just selected evidence, a simple scientific explanation exists to explain the so-called problem of Polonium (Po) halos. Robert Gentry's claim is that Po halos prove the Earth was instantly created. Of course, he only discusses the isotopes of 218Po, 214Po, and 210Po (products derived in 238Po disintegration) while ignoring the Po isotopes of other mass numbers (215Po, 211Po, 216Po, and 212Po) which are produced in the 235U and 232Th disintegration series. If included, these isotopes would invalidate his claims (Masson, S.L. and Garden, J.B., 1981. Radioactive mineral deposits of the Pembroke-Renfrew area: Ontario Geological Survey, Mineral Deposits Circular 23,155 p., accompanied by Preliminary Map P. 2210. scale 1:126,120.). And, as it turns out, if you examine the location where Mr Gentry collected his samples, you find that 253U and 232Th are present in the surrounding strata. Makes ya wonder, doesn't it? His logic follows the typical creationists style of ignoring contrary evidence.
I'm not geologist (and I'm sure someone else out there can explain this far better than I can), but I'm also not the type to simply trust what I'm told without trying to validate it from other sources. Guess what...I could not find any other evidence to support Mr Gentry's claims. Why did I try to find alternate explanations to the polonium halos? Is it because I trust in the ToE? Partly. But it also seemed rather foolish to me to think that one man (Robert Gentry) could be correct and that everyone else is incorrect. Think about it, which seem more likely? Robert Gentry is correct (the Earth was instantly created) and everybody else...geologists, astronomers, physisicts, biologists, etc..are all incorrect. Or could it be that Mr. Gentry based his results on faulty evidence and perhaps other explanations exist? It's typical of creationsists. They get the answer they want and then stop looking. Kinda sad really. SpinyNorman73, don't fall into the same trap.
