In absolute dating what radioisotope is used
If any of these three conditions is not accurately known, the hourglass will give an inaccurate measure of time.Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements.There are three main assumptions that must be made to accept radiometric dating methods.
The dates must be inferred based on assumptions about the ratios.Some of the common isotope pairs used are K-Ar, Rb-Sr, Pb-Pb, and U-Pb.Carbon-14 dating is another common technique, but it can only be used on carbon-containing things that were once alive.Far from being data, these dates are actually interpretations of the data.As discussed before, the assumptions influence the interpretation of the data.

If certain things are known, it is possible to calculate the amount of time since the parent isotope began to decay.
