Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. The use of radiometric dating was first published in 1907 by Bertram Boltwood and is now the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials. Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale. Among the best-known techniques are radiocarbon dating, potassium-argon datingand uranium-lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.
Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.

Can all radioactive isotopes be used in radiometric dating?
No, not all radioactive isotopes be used in radiometric dating. Some have very very short half lives and would entirely disappear before any useful period of time passed.
Why is igneous rock best for radiometric dating?
What method, and what materials, are best for dating depends on what exactly you are after.
What's the difference between a clock radio and an alarm clock?
A clock radio and an alarm clock are two very similar things which provide some of the same functions however they differ in their features. An alarm clock is a basic clock which has an alarm function and a clock radio combines the use of an AM/FM radio and an alarm clock.
Is there such thing as electric clock?
Well yes there is. it is sort of like an computer clock. it is also digital clock . and people say it as a electric clock.
What has two hands but can not hand?
a clock
When is the radiometric clock set in the lifetime of a rock?
The radiometric clock is set when the rock is formed. Because this is when it sets, radiometric dating is used by geologist to find out when the rock was formed.
When is the radiometric clock set in the lifetime of rock?
FALSE
Radiometric dating is least useful for dating what type of rocks?
Sedimentary Rocks
Which type of rocks are best for numerical dating using radiometric technique?
Igneous rocks
What is a radiometric clock?
Radiometric clocks are naturally occurring radioisotopes, such as 14C, with known half-lives, that are used to date organic materials.
Would you use uranium- lead radiometric dating to find an igneous rocks age?
would you use uranium-lead radiometric dating to finnd an igneous rocks age
What does radiometric dating tell geologist about some rocks and minerals?
their ages
What is dating used to date ancient rocks millions of years old?
Radiometric
How do scientist determine the ages of rocks?
They can use either radiometric dating or magnetostratigraphy.
Method of dating rocks when the amounts of parent and daughter materials are measured?
radiometric
Techniques used to date the Turin Shroud and rocks?
It's called radiometric dating.
When radiometric dating is applied to metamorphic rocks what is the date obtained?
Time since metamorphism.
