Limitations of radiometric age dating

While not all objects have the same isotopes, both living and nonliving objects have some sort of decaying, radioactive isotope that can be used based on known decay rates. An isotope of some sort is located and isolated within an object.That isotope is then compared to its decaying product and scientists are able to use known decay rates to determine how old the initial isotope is.Relative dating also uses the principle of association which is the comparison of two or more things to establish a relative age.For example, if two fossils are found at the same site but at different depths it will be assumed that the fossil found at the greater depth is older and therefore a relative time line can be established.

Radiocarbon dating is frequently used to date ancient human settlements or tools. It is a stable atom that will not change its atomic mass under normal circumstances.

In fact, radiometric dating can be used to determine the age of the Earth, (5.54 billion years old) other planets, and celestial objects.

Radiometric dating is often referred to as “radioactive dating” and “carbon dating,” though many different types of isotopes can be used to identify an object’s age.

I didn't ask if radiometric dating is valid and my question can't be answered by yes?

I asked specifically about reliability and limitations with the assumption, that the method itself is valid.

It can be answered with just a "yes." That's generally a sign of a bad question.
