A correction for the half-life is incorporated into calibration curves, so even though radiocarbon ages are calculated using a half-life value that is known to be incorrect, the final reported calibrated date, in calendar years, is accurate. Blenkinsop; Peter Buchholz; David Love; Thomas Oberthür; Ulrich The ratio of 14 C to 12 C in the atmosphere is taken as the baseline for the other reservoirs: if another reservoir has a lower ratio of 14 C to 12 C, it indicates that the carbon is older and hence that some of the 14 C has decayed. In fact, the level of 14 C in the atmosphere has varied significantly and as a result the values provided by the equation above have to be corrected by using data from other sources. Hemisphere effect The northern and southern hemispheres have systems that are sufficiently independent of each other that there is a noticeable time lag in mixing between the two.

This is done by calibration curves, which convert a measurement of 14 C in a sample into an estimated calendar age. There are a number of such isotopes. This method is also known as "beta counting", because it is the beta particles emitted by the decaying 14 C atoms that are detected. At a certain temperature, the crystal structure has formed sufficiently to prevent diffusion of isotopes.
