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 samples which can yield between 1g and 4g of carbon (eg ~15g wood taken from a house timber or 5-10g charcoal from an archaeological site) the dating procedure via benzene synthesis can be carried out in-house by RCD.The process usually takes 4-6 weeks to complete (Please phone to discuss any contemplated dating project with RCD before commencing any sample taking).Libby received the Nobel Prize for his work in 1960.

Suitable materials for carbon dating include: wood, charcoal, ivory, straw, hair etc.includes: sample pretreatment, benzene synthesis, counting, LS vial selection.C14 dating (radiocarbon) is performed in our laboratory using modern conventional (LSC based) method since 1993.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.
