includes all steps: sample pretreatment, benzene synthesis, counting, LS vial selection.C14 dating (radiocarbon) is performed in our laboratory using modern conventional (LSC based) method since 1993.Interestingly, this week, radiocarbon dating of rat bones from New Zealand raises the issue of just how “foolproof” this radiometric dating method is.The history of rats on New Zealand, while not a grade school topic, is important to the anthropologists who have tried to determine just when humans reached New Zealand.According to the commonly accepted theory, rats were stowaways (or perhaps brought as food) on the boats of the Polynesian explorers who first reached New Zealand.Thus, based on the 1996 carbon-dating of rat bones, some anthropologists concluded it was as early as 200 B.

when the first humans (and rats) reached the islands.

That study has been controversial, because anthropologists have found no legacies of human settlement that would date to that time period.

rates of decay, amount of initial concentration, presumption of a closed system, and so forth.

Instead, other anthropologists believe it wasn’t until the 13th century that rats and humans arrived.

But what to do with the carbon-dating results from the 1996 study?

Simple: it must have been a lab error, these anthropologists Radio analytics of the Institute of Hygiene and Medical Ecology located at Kyiv, Ukraine offers conventional radiocarbon(C14) dating services.
