WebSep 15, 2014 · The formulas for half-life are t ½ = ln2 λ and t ½ = t ln2 ln( N 0 N t). The equation for exponential decay is. (1) N t = N 0e−λt, where. N 0 is the initial quantity. N t is the quantity at time t. λ is the exponential decay constant. We can solve this for λ: 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… http://chemistry.about.com/od/nucleardecayproblems/a/Half-Life-Example-Problem.htm children\u0027s endocrinology
