First, not every living thing takes up carbon-14 equally, nor is every living thing exposed to the same amount of cosmic radiation.
The amount of cosmic radiation also changes with time and does not reach the earth equally over all regions.
It must be added to a very long compilation of forbidden knowledge in the United States.
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.
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.
Anyone who still believes that C14 dating has proven the Shroud to be medieval should be quickly disabused of that notion.
Scientists, using rigorous methods have established a process to eliminate this problem by calibrating radiocarbon dating results to items of a known age.
In this way, items of unknown age can be tested and an age determined to a reasonable degree of accuracy. More tomorrow where we explore the concept of isochron dating and how it neatly destroys most of the rest of these ‘issues’.
