Problem: -We are given the following atomic masses: 238 92 U = 238.05079 u. 4 2 He = 4.00260 u, 90 234 Th = 234.04363 u, 1 1 H= 1.00783 u, 237 91 Pa = 237.05121 u. Here the symbol Pa is for the element protactinium (Z = 91). (a) Calculate the energy released during the alpha decay of 238 92 U . (b) Show that 238 92 U cannot spontaneously emit a

Click to see full answer. An example of a nucleus that undergoes alpha decay is uranium-238. The alpha decay of U -238 is (17.3.1) U 92 238 → He 2 4 + Th 90 234 In this nuclear change, the uranium atom (U 92 238) transmuted into an atom of thorium (Th 90 234) and, in the process, gave off an alpha particle. Uranium has three primary naturally occurring isotopes isotopeA form of an element that has the same number of protons but a different number of neutrons in the nucleus, giving it a different atomic mass. For example, uranium has thirty-seven different isotopes, including uranium-235 and uranium-238.: U-238, U-235 and U-234.

Alpha Decay. The nuclear disintegration process that emits alpha particles is called alpha decay. An example of a nucleus that undergoes alpha decay is uranium-238. The alpha decay of \(\ce{U}\)-238 is \[\ce{_{92}^{238}U} \rightarrow \ce{_2^4He} + \ce{_{90}^{234}Th} \label{alpha1}\]
Isotope. 238 U. 238 U decays via alpha decay to 234 Th with half-life of ~4.5×10 9 years. 238 U occasionally decays by spontaneous fission with probability of 0.000055%. Its specific activity is very low ~3.4×10-7 Ci/g.
Gamma Radiation. Frequently, gamma ray production accompanies nuclear reactions of all types. In the alpha decay of \(\ce{U}\)-238, two gamma rays of different energies are emitted in addition to the alpha particle.
Solution: 238 U --> 237 Pa + 1 H. m(237 Pa) = 237.05121 u, m(1 H) = 1.00783 u. Q/c 2 = 238.05079 u - 237.05121 u - 1.00783 u = - 0.00825 u. The energy released is negative, we have to add energy to make this reaction possible.

Q/c 2 = 238.05079 u - 237.05121 u - 1.00783 u = - 0.00825 u. The energy released is negative, we have to add energy to make this reaction possible. In-class activity: Alpha decay The alpha radiation of the uranium isotopes U-238, U-235, and U-234 presents a radiation hazard on ingestion or inhalation, while the beta radiation of the short-lived decay products Th-234 and Pa-234m, together with the weak gamma radiation emitted by all nuclides, presents an external radiation hazard.
