The reliability of that calculation will in turn depend on other conditions.Given the complexity of radioactive dating, confirmation bias can also be a problem.It is impossible to measure the age of something, except to time it as it actually occurs, so radioactive dating methods calculate the age, based on (i) measurements of quantities of specified materials, (ii) measurements of decay rates, and (iii) assumptions about the history of the sample.Suppose we have a tank partly filled with water, and a hole in the bottom through which the water is leaking out of the tank.This arises when the person performing the analysis has a strong expectation of what the result should be.

We could measure (a) how much water the tank holds, (b) how much is still in the tank, and (c) the rate at which it is leaking out.

Several dozen methods exist, using different radioactive isotopes and decay products, with varied dating ranges and precision.

The procedure, however, is difficult, and many tests have shown that it can be inaccurate, and it is at times not even considered reliable by mainstream scientists.

As with any dating technique, there are some significant limitations.

Radioactive dating is the procedure of calculating an age for an artifact by determining how much of the radioactive material has decayed and calculating how long that would take given the half-life (how long it takes for half the material to decay) of the material being tested.
