Lesson Radioactive decay problems - Algebra
WebWhile it's impossible to know when a radioactive element will decay, it is possible to statistically know the average time it takes for a sample to decay to half of its original amount. This measure, called a half-life, is a crucial measurement in the dating of ancient artifacts and fossils. WebDec 28, 2024 · There are three equivalent equations that give the number of nuclei remaining at time t . The first is given by: N (t) = N_0 (1/2)^ {t/t_ {1/2}} N (t) =N 0(1/2)t/t1/2 Where t1/2 is the half-life of the isotope. The second involves a variable τ , which is called the mean lifetime, or the characteristic time: WebJul 12, 2024 · To find the half-life, we want to determine when the remaining quantity is half the original: 1 2a. Solving, 1 2a = a(0.87)d Divide by a, 1 2 = 0.87d Take the log of both sides log(1 2) = log(0.87d) Use the exponent property of logs log(1 2) = dlog(0.87) Divide to solve for d d = log(1 2) log(0.87) ≈ 4.977 days simon whittaker entries
