Question

An archeological artifact was subjected to radiocarbon dating. the artifact showed a carbon-14 decay rate of 13.8 disintegrations/min per gram of carbon. carbon-14 has a half-life of 5715 years, and currently living organisms decay at the rate of 15.3 disintegrations/min per gram of carbon. what is the approximate age of the artifact?

Answer 1

I would say that the approximate age of the artifact would be 13.8/15.3 x 5715=5154 years old assuming that the disintegration rate of the artifact is  proportional to the present disintegration rate and to the half-life age.
