Without understanding the mechanics of it, we put our blind faith in the words of scientists, who assure us that carbon dating is a reliable method of determining the ages of almost everything around us.However, a little more knowledge about the exact ins and outs of carbon dating reveals that perhaps it is not quite as fool-proof a process as we may have been led to believe.We hope that you find what you’re looking for, but mostly we hope you have a great time meeting and chatting to new people. At least to the uninitiated, carbon dating is generally assumed to be a sure-fire way to predict the age of any organism that once lived on our planet.

The authors expect determining the radiocarbon ages using only the calcium oxalate minerals, greatly improves the accuracy.This rate of decay, thankfully, is constant, and can be easily measured in terms of ‘half-life’.Half-life refers to the amount of time it takes for an object to lose exactly half of the amount of carbon (or other element) stored in it.A new technique, developed at ANSTO’s Centre for Accelerator Science, has made it possible to produce some of the first reliable radiocarbon dates for Australian rock art in a study just published online in The approach involved extracting calcium oxalate from a mineral crust growing on the surface of rock art from sites in western Arnhem Land, according to paper co-author research scientist Dr Vladimir Levchenko, an authority on radiocarbon dating using accelerator mass spectrometry.Levchenko, who supervised the radiocarbon dating, collaborated with lead author of the paper, Ms Tristen Jones, a Ph D candidate at the Australian National University (ANU) and co-authors from ANU.“These microorganisms are photosynthetic bacteria, like cyanobacteria or algae, which can utilise carbon from the air normally, and are active through wet periods,” said Levchenko.One of the peer review authors who reviewed the paper prior to publication predicted it could become a benchmark for studies of this type as it addressed a complete lack of chromometric data for rock art in Australia and elsewhere.Another reviewer called it the most significant rock art and dating paper to have been produced in Australia for over 25 years.The approach has produced an upper and lower limit of dates for a regional art style known as Northern Running Figures (NRF) or Mountford figures, believed to have been produced in Australia during the early to mid-Holocene (10,000 – 6,000 years ago).The C-12 is a very stable element and will not change form after being absorbed; however, C-14 is highly unstable and in fact will immediately begin changing after absorption.Specifically, each nucleus will lose an electron, a process which is referred to as decay.
