While the first only has one fast decay in the sub-chain (234Pa->234U), the second has two consecutive beta decays with comparable lifetimes (27' and 20'). The third also gives two beta electrons. In total, every 238U decay eventually produces 5 beta electrons, randomly distributed with a complex function of the listed lifetimes. Gå till mobilversionen av bokus.com.
