Uranium is known to undergo radioactive decay to form 206 Pb by emitting alpha and beta particles. A rock initially contained 68×10 g of 238U. If the number of alpha particles that it would emit during its radioactive decay of 232³ U to 326 Pb in three half-lives is Zx 10¹8, then what is the value of Z? 92 82 Uranium is known to undergo radioactive decay to form 206 Pb by emitting alpha and beta particles.
