C13 carbon dating

Then I noticed how it had a wide arrange of allotropes, and that did it; I squirted in my pants." Indeed, carbon daters find all the chemical properties of carbon inherently arousing, though the specifics often differ; many prefer it in its diamond form, while others prefer the radioactive isotope of carbon-14, actually finding it sexually arousing to get radiation sickness and die.

As the starting point, assume that the "true" age of the Shroud is 2000 years, and further accept that the measured radiocarbon age (about 600 years) is a good estimate of the radiocarbon that was present in the samples measured. Suppose that the bioplastic layer began at the time the cloth was made (2000 years ago) and has been growing uniformly ever since.

Then the carbon in the layer will have an average radiocarbon age of about 1000 years. Suppose that the Shroud remained growth-free right up to around the middle of the 20th century, when some process, or contamination, started the layer growing.

This organic material would of course be younger than the linen itself and would not have been removed in pretreatment.

As one who earns his crust doing accelerator mass spectrometry radiocarbon dating, I have to say that I have a few problems with the Garza-Valdes & Mattingly theory.

Anyone who still believes that C14 dating has proven the Shroud to be medieval should be quickly disabused of that notion.

See the most recent report by Garza Valdes re-printed on "bio- plastic coating" he found on Shroud fibers, in sufficient quantity to throw the date WAY off.Once a piece of carbon is found, the dater usually talks to it for several weeks, starting with only saying one sentence or two, then backing off so as not to seem intimidating.Some critics have asked, "Why not just pick up the carbon and rape it?This article is compiled from a series of postings that appeared on the Shroud Newsgroup, alt.turin-shroud.In it, Rodger Sparks, a carbon dating expert from New Zealand, and William Meacham, archaeologist and Shroud researcher from Hong Kong, debated some of the theories that have been proposed regarding possible inaccuracies in the 1988 carbon dating test results.Hence the growth must incorporate carbon from an external source, and to produce an age shift like that postulated, that source must be the atmosphere, whether by photosynthesis or some other mechanism.
