The a-decay of 238U (t,/2 = 4.47x10°y) leads to 234TH (t/2 = 24.1d). A sample of uranium ore should reveal 234TH activity in secular equilibrium with the parent. The isotopic abundance of 238U in natural uranium is 99.3%. A. What would be the 234TH activity in each gram of uranium? B. How big (length of each side of a cube) is 1 g of uranium? The density of uranium metal is 18.95 g/cm3.
