WebThis is made more complicated by the process of build-up. For example, if you have 218Po in your sample, it alpha decays to 214Pb with a half-life of 3 minutes. But, the 214Pb then beta-decays to 214Bi with a half-life of 27 minutes. Thus as the α activity goes down, the β activity goes up. In this example, the Bi then β decays with WebThis differs for each radioelement, ranging from fractions of a second to billions of years. For example, the half-life of Iodine 131 is eight days, but for Uranium 238, which is present …
