Ams dating rock art
In this brief paper, we argue that beeswax forms an important by-product of beekeeping and that its dates from this remote corner of Africa are synchronous with beeswax paintings found elsewhere, in particular, within pre- and post-colonial Australia. Rowe) One of the more frequently asked questions about rock art is: How old is it?Choosing the best method for radiocarbon dating depends on the quantity of available sample or, in the case of expensive materials, how much of it you can afford to be destroyed.AMS dating, for example, involves burning a sample to convert it to graphite.There was a revolution in our ability to answer that important question starting three decades ago (1977).The major advancement that laid the groundwork for the later dating revolution was the development of accelerator mass spectrometry (AMS).Tracer-Free AMS Dating Lab Beta Analytic does not accept pharmaceutical samples with "tracer Carbon-14" or any other material containing artificial Carbon-14 to eliminate the risk of cross-contamination.
Lower Congo rock art is concentrated in a region that stretches from Kinshasa to the Atlantic coast and from northern Angola to southern Congo-Brazzaville.Advantages of AMS Radiocarbon Dating over Radiometric Analysis by LSC:(a) small sample size needed (as little as 20 mg) thus it is recommended for radiocarbon dating of blood particles, grains, seeds, small artifacts, or very expensive or rare materials;(b) takes less time than radiometric method (less than 24 hours);(c) higher precision than radiometric techniques.AMS dating is an advanced method compared to radiometric dating using liquid scintillation counters (LSC). Samples submitted for radiometric dating will be reported as Radiometric PLUS, which combines large sample handling techniques with particle detection.Absolute dating demonstrated that beeswax application was not a recent event, but doesn't belong to Neolithic Period.Based on secure chronometric dating, the beeswax paintings of Goda Roriso are the oldest of their type outside Australia.

Precision for AMS carbon dating results will be better than radiometric dating (LSC) analysis for samples that are more than 10,000 years old.
