Clearly, such huge time periods cannot be fitted into the … Web30 Jun 2024 · There are two interrelated concepts with any form of radiometric dating: accuracy and precision. Accuracy refers to how close the assessed age of a sample is to the true age. Precision refers to the statistical uncertainty associated with an age estimate—the greater the precision, the less uncertainty there is in the assessed age.

Web17 Feb 2016 · Older carbon dating techniques directly detected decays of C14 atoms.
