Half-life in geology is defined as the time it takes for a radioactive material or element to decay half its original quantity into a daughter radiogenic isotope.
From the radioactive elements listed the Carbon-14 would be most preferable for dating a specimen.
What is radiometric dating?
Radiometric dating is defined as the process that is used by scientists to calculate the age of geologic materials.
From the data given in the table above, the radioactive element with the most recent half-life is carbon-14 being 5,730 years.
The uses os Carbon-14 include the following:
- Used to measure the age of wood,
- Used to measure sources of chloride and the age of water
- Researchers can use that decay as a kind of clock that allows them to peer into the past.
- Used in studying abnormalities of metabolism that underlie diabetes, gout, anemia, and acromegaly.
The carbon-14 is preferably used for dating specimen because it is the most stable and accurately dates archaeological artifacts.
