Archaeologists can use this method to date bone, teeth, plants, seeds, burned food remains, coprolites, wood, and any artefact that contains organic materials such as an iron axe head (iron cannot be tested using C14) with a wooden handle or a bronze spear with a wooden shaft.For example, C14 leaches at an accelerated rate from organic material saturated in water, especially saline water.Fourthly, for C14 to test accurately the artefact must have been protected from contamination.However, experimental evidence indicates that C14 decay is slowing down and that millennia ago it decayed much faster than is observed today.
Secondly, the theory behind C14 dating demands that there is the same rate of cosmic production of radioactive isotopes throughout time.
These atoms rapidly decay into radiocarbon-dioxide and along with ordinary CO2 are absorbed by living plants.
