Since then, the technique has been widely used and continually improved.This paper will focus on how the radiocarbon dating method works, how it is used by scientists, and how creationists have interpreted the results.

The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years.C must be younger than 50,000 to 100,000 years, assuming that adequate precautions have been taken to eliminate contamination.Carbon dating, like other radiometric dating methods, requires certain assumptions that cannot be scientifically proved.Theoretically, radiocarbon techniques have the ability to date samples to around 75,000 years, but the working threshold of reliable dating is around 50,000 years.
