Beta Analytic’s radiocarbon dating fees are inclusive of δ13C measurements by Isotope Ratio Mass Spectrometry (IRMS) and calendar calibration when applicable, δ18O for carbonates, and δD (deuterium) and δ18O for water.
The lab also offers C: N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C at no additional cost for samples sent for radiocarbon dating.
Using the INTCAL98 curve it is possible to convert radiocarbon years to calendar years by projecting the radiocarbon age onto the curve and observing the intercept on the calendar year axis.
This can be done manually, but there are now computer programs in the public domain which will provide a more consistent and accurate calibration.
RCD-Lockinge (RCD-Radio Carbon Dating) is a private laboratory specialising in the measurement of tritium and carbon-14 at low levels for numerous environmental, industrial and dating applications.
