On the other hand, the concentration of carbon-14 falls off so steeply that the age of relatively young remains can be determined precisely to within a few decades.

If a material that selectively rejects the daughter nuclide is heated, any daughter nuclides that have been accumulated over time will be lost through diffusion, setting the isotopic "clock" to zero.

For most radioactive nuclides, the half-life depends solely on nuclear properties and is essentially a constant.

It is not affected by external factors such as temperature, pressure, chemical environment, or presence of a magnetic or electric field.

All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.

Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.

Precision is enhanced if measurements are taken on multiple samples from different locations of the rock body.

These temperatures are experimentally determined in the lab by artificially resetting sample minerals using a high-temperature furnace.

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
