To an archaeologist examples of relative dating methods include

Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.

Geologists use radiocarbon to date such materials as wood and pollen trapped in sediment, which indicates the date of the sediment itself.

For example, fission track dating measures the microscopic marks left in crystals by subatomic particles from decaying isotopes.

Another example is luminescence dating, which measures the energy from radioactive decay that is trapped inside nearby crystals.

All radiometric dating methods measure isotopes in some way.
