Luckily, we are in a position to measure these fluctuations in samples which may be dated by other strategies. Tree rings may be counted and their radiocarbon content measured. From these records a “calibration curve” can be built (see figure 2, below). Since carbon-12 doesn’t decay, it’s a great benchmark towards which to measure carbon-14’s inevitable demise. The less radioactivity a carbon-14 isotope emits, the older it’s. And since animals and vegetation stop absorbing carbon-14 after they start to decay, the radioactivity of the carbon-14 that’s left behind reveals their age.
