no fuss dating Radiometric dating simplified

This video answers the following questions: How is radioactivity used to determine the age of a sample? What are some major errors in dates that have resulted from radiometric dating? In other news, I hope this shows you how you can solve any radioactive dating problem from a very tiny amount of info.

Moehlenpah, I'm thinking about getting back into dating. It's all related via some simple equations, so get familiar with them.

Steps for solving simple radiometric rock dating problems.

Check out my other videos on the limitations of radiometric age dating techniques as well as a work-through of a sample problem set.

Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of radioactive decay. Radiometric dating is a method used to date rocks based on the known decay rate of radioactive isotopes. Now, they do not give off enough radiation that you have to be afraid to pick them up, but they do contain naturally occurring radioactive elements like uranium, for example.

Learn about three common types of radioactive decay: alpha decay, beta decay and gamma decay. You simply subtract your birth date from the current date. It was also discovered that these elements decayed into other elements at fixed rates.

So we have to rely on something called radiometric dating to figure out the age of rock.

Radiometric Dating Techniques - How Do Other Kinds of Radiometric Dating Work?

Radiometric dating techniques measure the rate of decay of radioactive isotopes into stable chemical elements and the concentrations of these same radioactive isotopes and chemical elements found within specimens of igneous and metamorphic rock.

For example, Uranium-238, an unstable radioisotope, decays into Lead-206, a stable chemical element, with thirteen intermediate unstable radioisotopes in between (Uranium-238 decays into Thorium-234, which decays into Protactinium-234, and so on to Lead-206).

In this case, Uranium-238 is called the "parent" and Lead-206 is called the "daughter." Radiometric Dating Techniques Three Basic Assumptions Radiometric dating (with the exception of Carbon Dating) can only be used to date igneous and metamorphic rock.

There are three basic assumptions fundamental to every radiometric dating technique.
