Carbon 14 not used for dating
Are these high radiocarbon “ages” a problem for the biblical worldview? First, remember that no detectable should be present within these samples if they really are millions of years old.Despite this apparent difficulty for the recent-creation view, this is, in fact, a much more serious problem for the old-earth view!When today’s rates are used to calculate ages from certain radioisotope ratios, the results indicate that billions of years’ worth of nuclear decay of the heavier radioisotopes has occurred.But there is evidence that this decay occurred in accelerated “spurts,” Why the High Radiocarbon Age Estimates?Smallest Detectable Amount of Radiocarbon Sensitive instruments called acceleration mass spectrometers (AMS) are used to count the C/C ratio in a sample drops below 0.001 p MC?One can estimate this time by dividing 100 p MC by 2 repeatedly until the resulting number drops below 0.001 p MC.This value of 0.2 p MC is very close to the value of 0.195 p MC found within Figure 1.
Finally, although contamination can sometimes occur, it should not be assumed in a particular instance unless there are good reasons to believe that it has.
Radiocarbon Basics Carbon comes in three “varieties” or isotopes: C is 5,730 years.
Because carbon is expected to be thoroughly mixed throughout the biosphere, atmosphere, and oceans, living organisms (which continually “take in” carbon throughout their lifetimes) are expected to have the same C in their bodies begins to decrease.
We find that about 18 such halvings are required for the p MC value to drop below 0.001 (Figures 1 and 2).
(We could “round up” the value of 0.0007 p MC at 17 half-lives to 0.001 p MC, but the 0.00038 p MC at 18 half-lives is definitely below the detection threshold.) Since each half-life is 5,730 years, this means that no C has even been detected in diamonds, which some scientists claim are billions of years old!
Could this be a clue that radioisotope “clocks” might have “ticked” at different rates in the past, and that this variation in “ticking” is different for different radioisotopes?
