Age estimates can be cross-tested by using different isotope pairs.

Results from different techniques, often measured in rival labs, continually confirm each other.

If those rocks really have been sitting around on the moon for billions of years, I suspect that the the wide range of physical and chemical processes which occurred over that time period had a much more profound effect on the uncertainty of the age determination. Those who are committed to an ancient age for the earth currently believe that it is 4.

This is best illustrated by the radioactive age of a sample of diamonds from Zaire. Obviously, then, the minimum error in that measurement is 1.

Since a neutron has no charge, it must become positively charged after emitting an electron. We know how long it takes Rb to turn into Sr, so in principle, if we analyze the amount of Rb and Sr in a rock, we should be able to tell how long the decay has been occurring.

Of course, there are all sorts of uncertainties involved. Was Rb or Sr added to the rock by some unknown process?

Consequently, individual years can be identified by season, so there is no possibility of layers being confused.

Sediment columns giving an unbroken history for more than 25, years have been identified in about 30 locations around the world.

In fact, they track because radiometric data is accurate.

Of course, there are many problems with such dating methods, such as parent or which they take as evidence that radiometric dating is giving true ages, since it is .

of these processes in order to evaluate the reliability of radiometric dating.

Most likely, that is the least important source of error.

For dating back to about 35, years, sediment layers are precise.
