WebMar 23, 2024 · An ingenious application of half-life studies established a new science of determining ages of materials by half-life calculations. For geological dating, the decay … WebThe half - life for radioactive decay of ^14C is 5730 years. An archaeological artifact containing wood had only 80% of the ^14C found in a living tree. Estimate the age of the sample. WebFrom that it is a simple calculation to get the half-life (or any other fraction you might care to use). The equation is: N = N₀ e^(−λt) ... If any atom doesn't decay in that half-life, it still has a 50% chance of decaying over the next half-life. The fact that it didn't decay in the first half-life doesn't increase the probability of decay. brite star candles
