Carbon dating half life equation

A similar sample of freshly cut wood of the same type of tree had an activity of 15.3 cpm.

Animals eat the plants so they too have carbon-14 in their tissues.

Carbon-14 is decaying constantly with a half-life of 5720 years.

It has been determined that the rate of radioactive decay is first order.

We can apply our knowledge of first order kinetics to radioactive decay to determine rate constants, original and remaining amounts of radioisotopes, half-lives of the radioisotopes, and apply this knowledge to the dating of archeological artifacts through a process known as carbon-14 dating.

The dose I was given is -younger copy of an earlier document (in which case it is odd that there are no references to it in other documents, since only famous works tended to be copied), or, which is more likely, this is a recent forgery written on a not-quite-old-enough ancient parchment.

If possible, the ink should be tested, since a recent forgery would use recently-made ink.

In this equation, the units of measure for N and No can be in grams, atoms, or moles.

It does not matter as long as they are like measures.

, where r is a measurement of the rate of decay, k is the first order rate constant for the isotope, and N is the amount of radioisotope at the moment when the rate is measured.
