The fund consists of a set number of radiocarbon dates available on an annual basis that community archaeology groups or projects can apply for. For we will fund radiocarbon dates. The fund is not open to universities, students, professional archaeological organisations or large charities. It is directed specifically at community groups seeking to obtain radiocarbon dates on key samples from sites they have investigated. The application process is very simple. Just complete the form below and under "Sample Information" fill in all the boxes for your sample.

Scientists now use a device called an Accelerator MassSpectrometer AMS to determine the ratio of C to C which increasesthe assumed accuracy to about years. Radiocarbon years differ from calendar years because the former are dependent on the varying content of carbon in the atmosphere. In all cases careful precautions were taken to eliminate any possibility of contamination from other sources. If this assumptionis not true then the method will give incorrect dates. Br Thanks for great info I was iin search of this info for myy mission. RC and astronomy harmonize perfectly when you use the correct dates for Biblical events. Plot the gain against a time constant and the shape of the curve tells you the age of the ceramic.
We considered three possible causes of this difference: the old wood effect, reservoir effects, and diagenesis. We concluded that differences in the radiocarbon ages between materials from the inner and outer surfaces of the same pot were caused either by the freshwater reservoir effect or by diagenesis. Moreover, we found that the radiocarbon ages of carbonized material on outer surfaces soot of pottery from other wetland archaeological sites were the same as the ages of material on inner surfaces charred food of the same pot within error, suggesting absence of freshwater reservoir effect or diagenesis. Charred material adhering to pottery has been used frequently for radiocarbon dating at archaeological sites.
