From Figure 1, a value of 0.098 ≈ 0.1 p MC corresponds to 10 half-lives, or about 57,000 years.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.If so, this would explain the discrepancy between the radiocarbon method and other radioisotope techniques.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.Despite this apparent difficulty for the recent-creation view, this is, in fact, a much more serious problem for the old-earth view!Second, such large calculated ages are based on the C/C ratio has remained unchanged for tens of thousands of years.But the calculated dates will only be accurate if the assumptions behind the method are correct.
One of these assumptions is that nuclear decay rates have always been constant.
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.
In principle, this decay rate may be used to “date” the time since an organism’s death.
C/C ratio was 500 times smaller than today’s value, this would be equivalent to 100 p MC/500 = 0.2 p MC.
This value of 0.2 p MC is very close to the value of 0.195 p MC found within Figure 1.
