WebAug 8, 2024 · We can determine the amount of a radioactive isotope remaining after a given number half-lives by using the following expression: amount remaining = initial amount × (1 2)n. where n is the number of half-lives. This expression works even if the number of half-lives is not a whole number. Example 11.5.1: Fluorine-20. WebJust below are the amounts remaining after 2, 3, and 4 half-lives. (1/2) 2 = 0.25 (1/2) 3 = 0.125 (1/2) 4 = 0.0625. I would like to stress that the decimal amount is the amount that remains after a given number of half-lives.

If the initial activity of a sample of I-125 is 32,000 cpm, how much activity will be present in 178.2 days? We begin by determining how many half-lives are represented by 178.2 days: 178.2 days 59.4 days / half-life = 3 half-lives.
