Carbon dating cost
Knowing the limitations of this dating method can help avoid colossal archaeological misinterpretations that would otherwise distort history.
Radiocarbon or C14 dating employs complex systems of measuring the unstable isotopes in once living matter.
Secondly, the theory behind C14 dating demands that there is the same rate of cosmic production of radioactive isotopes throughout time.
The industrial revolution has belched hundreds of thousands of tons of carbon gases into the atmosphere increasing the C12 ratio and atomic weapons testing have increased neutron levels.
This increases the C12 content and interferes with the carbon ratio.
These anomalies have driven archaeologists to question their earlier conclusions about archaeological sites and their respective civilizations founded on artefact dating.Nitrogen atoms in the upper atmosphere are struck by cosmic radiation and create C14 atoms.These atoms rapidly decay into radiocarbon-dioxide and along with ordinary CO2 are absorbed by living plants.change in ratio over time can be used to measure the age of organic samples.
Measurable samples have ages of between 150 and 50,000 years old.
Hence, the term ‘half-life’ was given to radioactive substances.
