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?If so, this would explain the discrepancy between the radiocarbon method and other radioisotope techniques.
One of these assumptions is that nuclear decay rates have always been constant.
Although C decays fairly quickly, heavier isotopes (such as uranium-238) decay much more slowly.
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.
Because the present decay rates of these heavier isotopes are so small, the assumption that these rates have always been constant naturally leads to age estimates of millions and even billions of years.
Interestingly, however, some radioisotope methods tend to consistently yield younger age estimates than others, even when the techniques are used on the same rock units.
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.
However, these excessively long ages are easily explained within the biblical worldview, and C should be present in specimens that are even a little more than 100,000 years old!
Nearly anyone can verify this for themselves using basic multiplication and division.
Radiocarbon Basics Carbon comes in three “varieties” or isotopes: C is 5,730 years.
