Also the argon-argon dating technique can be used for the potassium-argon sequence to ensure that no initial and half-life of the parent isotope, which can be obtained from tables such as the one given in [1]: Although radiometric dating is accurate in principle, the precision is very dependent on the care with which the procedure is performed.The possible confounding effects of initial contamination of parent and daughter isotopes have to be considered, as do the effects of any loss or gain of such isotopes since the sample was created.

Therefore, in any material containing a radioactive nuclide, the proportion of the original nuclide to its decay product(s) changes in a predictable way as the original nuclide decays.

Precision is enhanced if measurements are taken on different samples taken from the same rock body but at different locations.

Alternatively, if several different minerals can be dated from the same sample and are assumed to be formed by the same event and were in equilibrium with the reservoir when they formed, they should form an isochron.

Finally, correlation between different isotopic dating methods may be required to confirm the age of a sample.

The precision of a method of dating depends in part on the half-life of the radioactive isotope involved.

Poor vacuum permits gaseous atoms to intercept ionised atoms which are meant to be measured.
