Because of this, radon mitigation systems can be life-savers.
Imagine we have an undiscovered element, Parentium, that has a radioactive isotope, Parentium-123, which decays to stable Daughterium-123.
A mathematical formula can be used to calculate the half-life from the number of breakdowns per second in a sample of the isotope.
Some isotopes have very long half-lives, measured in billions or even trillions of years.
In order to understand the dynamics of cultural phenomena, scientific dating in archaeology is an increasingly indispensable tool.
