what is isotope dating

This provides a value for the background radiation, which must be subtracted from the measured activity of the sample being dated to get the activity attributable solely to that sample's 14 C. This is the reverse of the way the curve is constructed: a point on the graph is derived from a sample of known age, such as a tree ring; when it is tested, the resulting radiocarbon age gives a data point for the graph. Lund: Lund University. This is the principle of original horizontality : layers of strata are deposited horizontally or nearly horizontally Figure 2. The precision of a dating method depends in part on the half-life of the radioactive isotope involved. Chuan He. Measurement of N , the number of 14 C atoms currently in the sample, allows the calculation of t , the age of the sample, using the equation above.
