"WebThis probability amounts to 50% for one half-life. In an interval twice as long (2 T) the nucleus survives only with a 25% probability (half of 50%), in an interval of three half-life periods (3 T) only with 12.5% (half of 25%), and so on. You can't, however, predict the time at which a given atomic nucleus will decay. " - How does half life work radioactive decay

This yields:

WebJan 11, 2024 · The simple reason why the number of decays (strictly, the number of decays per unit time) decreases in simple radioactive decay is because there are fewer atoms left to decay. Nuclear decay is probabilistic. The probability of any given unstable atom decaying is constant (independent of time or the environment). WebFeb 16, 2024 · In summary, a half-life is simply a different way of presenting a constant rate of decay. (Keeping in mind that a constant RATE of decay, delivers progressively smaller decay as the amount of un-decayed material reduces.)
