For example, you may want to date a zircon crystal using a secondary ion microprobe (SIMS).This technique bombards the sample, slowly drawing material out and then sending it through to an ion counter.In order to do this, you need to measure various isotopes of uranium .

However, samples must be taken from several different areas of the object being studied to ensure maximum accuracy.
Also, radiometric dating relies on the principle that the isotope has remained in the object since its creation.
This is then transformed into isotopic ratios and then used to date the material.
The machinery you use has to be tuned and calibrated to which isotopes you want to measure and needs to be set with the correct running conditions.
Modern Radiometric Dating Techniques Modern radiometric dating uses many different techniques to identify both organic and inorganic objects.
