Best answer: a radiometric half life refers to the length of time it takes for half of a given amount of radioactive material to decay this is used in radiometric dating of many samples in archeology and geology.

  • The assumptions that are used in radiometric dating techniques are perfectly justified given if all we had was the radiometric techniques that i’ve.
  • Radiometric dating is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products.

Catégories how is radiometric dating used what is the difference between relative dating and radiometric dating how radiometric dating works how radiometric dating works. Radiometric dating is the determination of the date at which materials were formed by analyzing the decay of radioactive isotopes that were incorporated into the material when it was created and which presumably have not diffused out. Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods this uses radioactive minerals that occur in rocks and fossils almost like a geological clock.
