In 1903, Rutherford and Soddy proposed the concept of half-life, revealing the probabilistic nature of the quantum world.
Conversion Details
Half-life is the time required for half of the atomic nuclei in a radioactive sample to decay.
For example, Carbon-14 has a half-life of ~5730 years, while Iodine-131 is ~8 days.
