WebP eople who ask about carbon-14 (14 C) dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history.. Clearly, such huge time periods cannot be fitted into the … Web17 Feb 2016 · Older carbon dating techniques directly detected decays of C14 atoms. The problem: If the material is too old, the small amount of C14 present may not decay in the measurement interval. Newer, more accurate techniques use mass spectroscopy. Mass spectroscopy, like any man-made measurement, is not perfect. In particular, given a pure …

"WebAs a result of the open and closed system dynamics, the sample error (or the amount of uncertainty in dating a sample) often depends on the degree to which the sample is itself an open or closed system. If it’s more of an open system, you can get matter which incorporates outside thorium content into the sample. " - Uncertainty of radiometric dating
