Question

A fossil is found to have a 14c14c level of 73. 73. 0 ompared to living organisms. how old is the fossil?

Answer 1

If the 14C level of fossils is 73% compared to living organisms. It will be 2602 years.

What is radiocarbon dating?

This method is used to estimate the relative age of carbon-based materials. This is done usually for fossils which originate from living organisms.

This age is estimated by estimating the percentage of carbon-14 isotopes in the fossil. This is done by comparing this percentage to a reference standard used internationally. This method is of tremendous use in palaeontology. It has also found its use in hydrology, oceanography, geology etc.

Fossil age is determined by

At = (Ao) x (1 - 0.5)^(t/h)

Here, At/Ao = 0.73

So, 0.73 = 0.5^(t/5730)

Therefore, t = 2602 years
