In principle, this decay rate may be used to “date” the time since an organism’s death.But the calculated dates will only be accurate if the assumptions behind the method are correct.Yet this assumption leads to a contradiction: If these organic samples really are many millions of years old, then they should be radiocarbon “dead.” But they aren’t! Evolutionists have attempted to blame these surprising results on a number of mechanisms. Furthermore, laboratories take great pains to keep contamination to a minimum, and researchers have found that, provided a sufficiently large testing sample is used (in the ballpark of 100 milligrams or so), the amount of such possible lab contamination is negligible compared to the C already present within the specimen.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.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?If the scientist did not realize that the pre-Flood C/C ratio was hundreds of times smaller than today’s value, he would calculate the animal’s age to be approximately 9 × 5,730 years = 51,570 years old—even though it had just died!
Although C decays fairly quickly, heavier isotopes (such as uranium-238) decay much more slowly.Creation scientists have estimated (based upon the amounts of organic matter thought to be contained within the sedimentary layers) that the carbon in the pre-Flood biosphere may have been 300 to 700 times greater than what is present in today’s world.C/C ratio was 500 times smaller than today’s value, this would be equivalent to 100 p MC/500 = 0.2 p MC.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!

This value of 0.2 p MC is very close to the value of 0.195 p MC found within Figure 1.
