    Sources of error in radiocarbon dating

    k = σ) The tree ring data set for the years between 14 used Belfast Irish oak.

    The University of Washington (Seattle data set) supplied most of the measurements. sample 3 linen from Cleopatra’s Mummy, age measured by scintillation counting = 2,010 ± 80 yr BP.

    I found several good sources, but none that seemed both complete enough to stand alone and simple enough for a What is radiometric dating?

    Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock.' It relies on three basic rules, plus a couple of critical assumptions.

    ) state that counting statistics do not represent all the uncertainties in radiocarbon dating and that the errors resulting from type of sample, preparation and laboratory differences are difficult to quantify.

    A nuclide of an element, also called an isotope of an element, is an atom of that element that has a specific number of nucleons.The rules are the same in all cases; the assumptions are different for each method.To explain those rules, I'll need to talk about some basic atomic physics. Hydrogen-1's nucleus consists of only a single proton.An error multiplier, k = 1.3, was assigned to the Seattle data, additional variability in measurements was assigned to the data sets from Belfast and from Waikato, New Zealand (see Table 1). sample 4 cope from St Louis d'Anjou dated at ~ AD 1290 – 1310.The offset was determined by inter-laboratory comparisons. A chi square was calculated for the five data sets in order to determine whether the errors from the individual measurements adequately represented the total error.
