Measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying atoms in the sample and not just the few that happen to decay during the measurements; it can therefore be used with much smaller samples (as small as individual plant seeds), and gives results much more quickly.

of Radio analytics of the Institute of Hygiene and Medical Ecology located at Kyiv, Ukraine offers conventional radiocarbon(C14) dating services.It operate by benzene synthesis line and liquid scintillation counting based on Quantulus LSC.The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.

For all LS measurements we use LS spectrometer Quantulus 1220 more about your interest and requirements. Information on radiocarbon dating sample's submitted sizes required, you could find below.

We would like to discuss a radiocarbon(C14) concerned projects and other radioisotope researches especially from early stage of planning at Kyiv C14 lab. Please inform us about your planes for carbon dating in our laboratory prior to sample submission.

The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.

Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).
