Isotopic systems that have been exploited for radiometric dating have halflives ranging from only about 10 years eg tritium to over 100 billion years eg samarium147 for most radioactive nuclides the halflife depends solely on nuclear properties and is essentially a constant.

radioactive dating shows the oldest moon rocks are about 46 billion years old scientists infer that earth is only slightly older than those moon rocksroughly 46.

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes learn about halflife and how it is used in different dating methods such as uraniumlead dating and radiocarbon dating in this video lesson.

radioactive dating carbon14 c14 a radioactive isotope of carbon is produced in the upper atmosphere by cosmic radiation the primary carboncontaining compound in the atmosphere is carbon dioxide and a very small amount of.

Radioisotope dating also referred to as radiometric dating is the process of estimating the age of rocks from the decay of their radioactive elements there are certain kinds of atoms in nature that are unstable and spontaneously change.

Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere taking in carbon dioxide from the air for photosynthesis.

A commonly used radiometric dating technique relies on the breakdown of potassium 40 k by all living things when living things die they stop taking in carbon14 and the radioactive clock is set any dead material incorporated with sedimentary deposits is a possible candidate for carbon14 dating.

Thermoluminescence dating or tl dating uses the fact that radioactive decays cause some electrons in a material to end up stuck in higherenergy orbits the number of electrons in higherenergy orbits accumulates as a material experiences more natural radioactivity over time.

People who ask about carbon14 14 c dating usually want to know about the radiometric1 dating methods that are claimed to give millions and billions of yearscarbon dating can only give thousands of years people wonder how millions of years could be squeezed into the biblical account of.
