# Application isotopes carbon dating

Although relative dating can work well in certain areas, several problems arise.

Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.

More recently is the radiocarbon date of 1950 AD or before present, BP.

There are two techniques for dating in archaeological sites: relative and absolute dating.

A useful application of half-lives is radioactive dating.

This has to do with figuring out the age of ancient things.

Some of the application of tracer techniques are discussed below.It takes a certain amount of time for half the atoms in a sample to decay.It then takes the same amount of time for half the remaining radioactive atoms to decay, and the same amount of time for half of those remaining radioactive atoms to decay, and so on. The amount of time it takes for one-half of a sample to decay is called the half-life of the isotope, and it’s given the symbol: It’s important to realize that the half-life decay of radioactive isotopes is not linear.One of the interesting applications of radioactive decay is the technique of radioactive dating.Radioactive dating allows the estimation of the age of any object which was alive once, using the natural radioactivity of .
