In this problem, we are given that it takes 444 years for the substance to lose 1/2 of its radioactive nuclei, so in each year, it will tick through only one-444th of its half-life. So our exponent is t/444.
Web8 de ago. de 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. Web31 de ago. de 2024 · λ = decay constant. t = time. From the above formula we can say that to find half- life we need λ or half-life to find which can be found by quantification that is decay in the time interval. From the experiment half – life of U235is 7.04×108 years.
