Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.

The UK’s buildings account for almost half of the nation’s greenhouse gas emissions.
For centuries we have been building inefficiently, without sufficient insulation and using outdated heating systems that lose up to 70pc of their energy.
The producers made Warner’s lesbian relationships a focus of the show, and she had three different girlfriends — Mimi Saraiva, Rebecca Cardon and Brianna Stockton — during the course of three seasons.She went into a downward spiral: “To be honest, I felt a bit lost and started partying a lot. Jackie realized she needed to accept responsibility for her actions and devise a plan to pull herself out of her misery.It felt like I was taking a few steps backward in life and I started making bad decisions.” . “I quit drinking for a year and I quit dating for a year,” she continues, adding that she prayed for guidance every morning and night and cut “almost everyone” out of her life including friends, business partners, managers, lawyers. The former star of Work Out went to lunch earlier in the day, drank one martini and took an Uber home, sources close to Jackie told TMZ.So, if you know the radioactive isotope found in a substance and the isotope's half-life, you can calculate the age of the substance. Well, a simple explanation is that it is the time required for a quantity to fall to half of its starting value.So, you might say that the 'full-life' of a radioactive isotope ends when it has given off all of its radiation and reaches a point of being non-radioactive.Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.
