The quantity of the C remaining is measured by counting the beta radiation emitted per minute per gram of material. Thus there is co-relation between the rings of one tree to that of another. Archaeologists conducting a survey Archaeologists also use non-invasive techniques to survey sites known as remote sensing. Therefore as soon as the organism dies no further radiocarbon is added. But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating.
