Australia has two machines dedicated to radiocarbon analysis, and they are out of reach for much of the developing world.

In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.

Please contact us to discuss these prior to sending samples.

There are several things that you might want to check for.

Macrobotanical Identification may be requested for both Charcoal and Wood submissions.

Prior to processing for radiocarbon dating, a sub-portion of each submitted sample is prepared and sent to Paleoscapes Archaeobotanical Services Team for analysis.

A huge amount of work is currently underway to extend and improve the calibration curve.

In 2008 we could only calibrate radiocarbon dates until 26,000 years.The calibrated date is our “best estimate” of the sample’s actual age, but we need to be able to return to old dates and recalibrate them because new research is continually used to update the calibration curve.The second difficulty arises from the extremely low abundance of C, making it incredibly difficult to measure and extremely sensitive to contamination.This is affected by solar activity and the earth’s magnetic field.Luckily, we can measure these fluctuations in samples that are dated by other methods.Shipping and handling charges are estimated and added to the quoted cost.
