Carbon 14 dating assumes that the carbon dioxide

Libby was the American physical chemist who developed the carbon-14 dating technique.

This method is used to determine the age of ‘once living’ objects up to approximately 50,000 years.

If you measure the amount of carbon-14 in a once living object, you can determine the approximate age of the organism.

Carbon-14 dating is a great tool to get approximate ages of objects made up of natural materials like cloth and wood.

Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.Hess proposed the source of radiation came from outside the atmosphere.His theory was proved true by Robert Millikan determined the source of Hess’ detected radiation and called it “cosmic rays”.When the living thing dies, it stops absorbing new carbon-14.The natural ratio begins to change as carbon-14 decays.
