"Half-life (symbol t½) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely, non-exponential) decay. For example, the medica… " - Shortest element half life

Splet14. dec. 2024 · Radioactive material with a short half life is much more radioactive (at the time of production) but will obviously lose its radioactivity rapidly. No matter how long or short the half life is, after seven half lives have passed, there is less than 1 percent of the initial activity remaining. SpletThe radioactive decay law states that the probability per unit time that a nucleus will decay is a constant, independent of time.This constant is called the decay constant and is denoted by λ, “lambda.” One of the most useful terms for estimating how quickly a nuclide will decay is the radioactive half-life (t 1/2).The half-life is defined as the amount of time it takes for …
