Radiometric Dating The aging process in human beings is easy to see. Radioactive Decay The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. Half-Life So, what exactly is this thing called a half-life? Uranium-Lead Dating There are different methods of radiometric dating that will vary due to the type of material that is being dated.

Radiometric Dating

Potassium-Argon and Rubidium-Strontium Dating Uranium is not the only isotope that can be used to date rocks; we do see additional methods of radiometric dating based on the decay of different isotopes. Radiocarbon Dating So, we see there are a number of different methods for dating rocks and other non-living things, but what if our sample is organic in nature?

These samples are carefully cataloged and analyzed with a mass spectrometer. The mass spectrometer is able to give information about the type and amount of isotopes found in the rock.

Dating Fossils – How Are Fossils Dated?

Scientists find the ratio of parent isotope to daughter isotope. By comparing this ratio to the half-life logarithmic scale of the parent isotope, they are able to find the age of the rock or fossil in question.

There are several common radioactive isotopes that are used for dating rocks, artifacts and fossils. The most common is U U is found in many igneous rocks, soil and sediment. U decays to Pb with a half-life of million years. Due to its long half-life, U is the best isotope for radioactive dating, particularly of older fossils and rocks.

C is another radioactive isotope that decays to C This isotope is found in all living organisms.

How Is Radioactive Dating Used to Date Fossils? | Sciencing

One of the most commonly used methods for determining the age of fossils is via radioactive dating a. Radioisotopes are alternative forms of an element that have the same number of protons but a different number of neutrons. There are three types of radioactive decay that can occur depending on the radioisotope involved: Alpha radiation can be stopped by paper, beta radiation can be stopped by wood, while gamma radiation is stopped by lead.
