The isochron techniques are partly based on this principle.
The use of different dating methods on the same rock is an excellent way to check the accuracy of age results.
The simplest means is to repeat the analytical measurements in order to check for laboratory errors.
Some [skeptics] make it sound like there is a lot of disagreement, but this is not the case.
The disagreement in values needed to support the position of young-Earth proponents would require differences in age measured by orders of magnitude (e.g., factors of 10,000, 100,000, a million, or more).
Several hundred laboratories around the world are active in radiometric dating.
Their results consistently agree with an old Earth.
