Rubidium strontium dating calculator
Instead, they are a consequence of background radiation on certain minerals.
To calculate the age of a substance using isotopic dating, use the equation below: Ra has a half-life of years.
Chemists and geologists use tritium dating to determine the age of water ocean and fresh.
In addition, tritium dating can be useful in determining the age of wines and brandies.
Radioactive Dating Using Nuclides Other than Carbon Radioactive dating can also use other radioactive nuclides with longer half-lives to date older events.
For example, uranium which decays in a series of steps into lead can be used for establishing the age of rocks and the approximate age of the oldest rocks on earth. In a sample of rock that does not contain appreciable amounts of Pb, the most abundant isotope of lead, we can assume that lead was not present when the rock was formed.
