Define radioactive half-life
WebHalf-life is a measure of the time it takes a radioactive sample to decrease its mass or quantity by half and, among other things, its danger. However, the half-life isn’t just about … 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 medic…
