Its standard AMS dating service has a turnaround time of 14 business days.It is dedicated to the advancement of fundamental research, education, methods development and service."Radiocarbon" the journal of record of the field, has been published by the Arizona Board of Regents since 1989.An accelerator then increases the kinetic energy of the carbon ions to 10-30 million electron volts and moves them through a tube where a powerful electromagnet makes them change direction. Because carbon-14 decays over time, the amount of it in a sample indicates the age of the sample.

How much their path bends depends on their mass: Lighter ions bend more. Penn State will soon be home to an accelerator mass spectrometer (AMS) that will allow researchers all over the country to do high-precision carbon dating to address questions about Earth's past and present.

The following file includes the record of all radiocarbon dates that have been processed at Brock University since the lab began operation in 1971.
