This makes the plant appear to have died many more years ago than it actually did (for example, the plant might appear to be, say, 3,000 years old, rather than 2,000) Carbon-14 dating—explained in everyday terms. Both carbon dating methods have advantages and disadvantages A major breakthrough in carbon-14 dating occurred with the introduction of the accelerator mass spectrometer. May 22, 2002 · Accelerator mass spectrometry (AMS), a sensitive radiometric dating technique, is in some cases finding trace amounts of radioactive carbon-14 in coal deposits, amounts that seem to indicate an age of around 40,000 years.
