Radiocarbon dating sample size Maine dating strap on

Rated 4.13/5 based on 650 customer reviews

The second is a set of new samples that the RATE team collected and sent to a leading radiocarbon AMS laboratory to be dated.

More processing tends to introduce more contamination.

Most laboratories prefer to receive samples larger than 1 mg to allow some loss in cleaning and to have additional material available if needed.

Modern radiocarbon dating by AMS is a complex process with numerous potential sources of contamination requiring characterization.

But the amount of contamination is generally impossible to quantify.

An old sample with in situ contamination cannot generally provide an accurate date.
