How accurate is carbon dating

Rated 3.94/5 based on 641 customer reviews

But it is already clear that the carbon method of dating will have to be recalibrated and corrected in some cases.

Scientists at the Lamont-Doherty Geological Laboratory of Columbia University at Palisades, N.

Elements can be transported into a sample or leach out of a sample.

Scientists will reject theories about the age of the earth that do not conform to the norm.

d) Even if the rate of decay is constant, without knowledge of the exact ratio of carbon-12 to carbon-14in the initial sample, the dating technique is subject to question.

New research shows, however, that some estimates based on carbon may have erred by thousands of years.

It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said.

This assumption is backed by numerous scientific studies and is relatively sound.

However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.
