Three additional assumptions are necessary in radiocarbon dating in order to estimate the initial concentration of C could be caused by changes in the intensity of the cosmic radiation or in the strength of the earth’s magnetic field.

Carbon-14 dating cannot be applied to materials that have no C dates are less than that figure.
