Uran-238-isotopen reagerar med en isotope (fermium-258)—for radioactive decay by spontaneous fission (370 av S Baum — length of the 234Th recoils from (234U → α + 234Th) decays.

Alpha decay of the 238U "parent" nuclide, for example, produces 234Th as the "daughter" nuclide. 238 234 4 U → Th + He (a-decay) 92 90 2 The sum of the mass numbers of the products (234 + 4) is equal to the mass number of the parent nuclide (238), and the sum of the charges on the products (90 + 2) is equal to the charge on the parent nuclide. Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234, and so on. The various decay products, (sometimes referred to as “progeny” or “daughters”) form a series starting at uranium-238. Click to see full answer. An example of a nucleus that undergoes alpha decay is uranium-238.
