Setengahhidup

Setengahhidup, also known as half-life, is a term primarily used in nuclear physics and chemistry to describe the time required for a radioactive substance to decay to half of its original quantity. This measure is a characteristic property of each radioactive isotope and indicates its rate of decay.

The concept of half-life is essential in understanding the stability and longevity of radioactive materials. It

Half-life is mathematically expressed through exponential decay models. If N0 is the initial quantity of a

This decay process occurs because unstable atoms spontaneously emit radiation, such as alpha, beta, or gamma

Understanding half-life is critical in fields like radiometric dating, nuclear medicine, and nuclear power management. It

In summary, half-life is a fundamental property that describes the time it takes for half of a
