You need a device to measure this activity (a thermometer, of which various kinds exist).

To understand radiometric dating techniques, you first have to have an understanding of what is being measured, how the measurement is being made and the theoretical as well as practical limitations of the system of measurement being used.

As an analogy, say you find yourself wondering, "How warm (or cold) is it outside?

Mathematically, from the above equations, this is N/N The trick is knowing which of the various common radioactive isotopes to look for.

This in turn depends in the approximate expected age of the object because radioactive elements decay at enormously different rates.U-Pb dating is often used to date igneous (volcanic) rocks, which can be hard to do because of the lack of fossils; metamorphic rocks; and very old rocks.
