The carbon content of Cqrbon trees includes a small proportion of carbon, which is a radioactive isotope. After a tree dies, the proportion of carbon in it decreases due to radioactive decay.
The age of an ancient boat may be determined by comparing the radioactive decay of from living wood with that of wood taken from the ancient boat. A sample of 3.
In living wood one in 10 12 of the carbon atoms is of the radioactive isotopewhich has a decay constant of 3. The age of a piece of bone recovered from an archaeological site may be estimated by 14 C dating. All living organisms absorb 14 Physixs but there is no further intake after death.
The proportion of 14 C is constant in living organisms. A 1 g sample of bone from an archaeological site has an average rate of decay of 5.
A 1 g sample of bone from a phydics skeleton has a rate of decay of 6. The counts are corrected for background radiation.
