Radio carbon dating service toronto
The issues of sample size and the role of rust are important because they open up new possibilities for dating iron-based artefacts that had previously been assumed to be unavailable.
Tusks seized from a Toronto auction house proved to be from an elephant killed around 1978, which are illegal.
Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for Carbon-14 measurements.
The radiocarbon dating lab is based in Miami, Florida, and is the world leader in Carbon-14 analyses since 1979.
The samples were dated with the rust that had accumulated over the last 30 years, which in some cases had consumed most of the original metal.
The study also afforded the opportunity to compare beta counting with accelerator mass spectrometry, large and small sample sizes, and old versus new carbon extraction methods.

We reserve the right to close comments at any time.In just the past 10 years over 25,000 samples have been measured from clients in New Zealand and throughout the world.As well as the AMS facility, the Rafter Radiocarbon Laboratory operates a modern, well equipped sample processing laboratory.The role of rust in the radiocarbon dating of iron artefacts has been examined experimentally.This was accomplished by re-measuring, using modern accelerator mass spectrometry techniques, the radiocarbon dates of ancient iron-based artefacts that were originally radiocarbon dated 30 years ago by beta counting.
