In order to resolve this discrepancy within a certain tolerance, calibration charts are often used to mediate the readings.
Various calibrations may include distortions caused by magnetic disturbances or abnormally high C-14 concentrations found in the vicinity of the fossil's environment.4.
As such, the absorption rate is fairly constant, that is, until death starts to kick in.
When an animal dies, the animal stops absorbing carbon, for the obvious reason that it no longer can consume food.
In recognition of his work, he was awarded the Nobel Prize in chemistry in 1960.
In short, it takes 5,700 years to reduce C-14 by 50%, another 5700 years to reduce to 25%, and so on, at an exponential rate.
The formula for C-14 dating is:t = [ ln (Nf/No) / (-0.693) ] x t1/2-ln is the natural logarithm;-Nf/No is the percent of carbon-14 in the sample compared to the amount in living tissue;-t1/2 is the half-life of carbon-14 (5,700 years).
Often times, I have come across websites, such as "Answers In Genesis" (Judging from the title, it is obvious that this website isn't really about Science), which shamelessly debunk the basic tenets and empirical methods of Science.
Being the intellectual equivalent of hucksters and mobsters, Creationists of these sort are apt to criticize the Scientific Method in a bid to construe evidence to fit into their biblical bullshit.
The truth is, C-14 decomposition is highly consistent, with a margin error of plus or minus 40 years.
