WebHalf-life (symbol t ½) 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 … WebHalf-Life Calculator Use this decay calculator to easily calculate the time elapsed since the beginning of the decay, or calculate the original quantity, half-life (a.k.a. decay rate) or …

WebProblem #3: Os-182 has a half-life of 21.5 hours. How many grams of a 10.0 gram sample would have decayed after exactly three half-lives? Solution: (1/2) 3 = 0.125 (the amount remaining after 3 half-lives) 10.0 g x 0.125 = 1.25 g remain 10.0 g − 1.25 g = 8.75 g have decayed Note that the length of the half-life played no role in this calculation. WebFor example, technetium-99m, one of the most common medical isotopes used for imaging studies, has a half-life of 6 hours. The short half-life of technetium-99m helps keep the dose to the patient low.
