A (federally-funded) handling and analysis surcharge applies to small samples (2-9 µmol).
For example, if there were 10 grams of carbon-14 in a living thing’s body 5.570 years ago, then there will now be only 5 grams.
This test, like other radiometric tests, cannot be used to determine the age of specimens which are thought to be very old, since carbon-14 has only a short half-life.
There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry (AMS).
The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.
In this way, every living thing on Earth absorbs an equal level of carbon-14 into its body.
When that plant or an animal dies, it is of course no longer able to feed and absorb any more carbon-14.Evolutionists use this method in order to determine age when examining the fossil record.However, as with other radiometric tests, there are serious doubts concerning the reliability of carbon-14 dating.These two radiocarbon dating methods use modern standards such as oxalic acid and other reference materials.Although both radiocarbon dating methods produce high-quality results, they are fundamentally different in principle.Carbon-14 dating is regarded as giving accurate results for specimens between 10,000 and 60,000 years old.
