The quantity of the C remaining is measured by counting the beta radiation emitted per minute per gram of material. These changes obviously effect the flora and fauna, which try to adapt to the condtions by subjecting some changes in the body structure. The second difficulty is that the radio active decay does not take place at a uniform rate but is a random process, and is therefore, governed by the laws of statistical probability.
