The radioactive decay series of 232 Th is complex and produces alpha, beta, and gamma radiation. The figure below shows the important isotopes in the decay series, indicates whether the primary decay mode is via alpha or beta emission, and gives the half-life.

Problem: The radioactive decay of thorium-232 occurs in multiple steps, called a radioactive decay chain. The second product produced in this chain is actinium-228. Which of the following processes could lead to this product starting with thorium-232?(a) Alpha decay followed by beta emission(b) Beta emission followed by electron capture(c) Positron emission followed by alpha decay(d) Electron

4 He nuclei are produced during radioactive decay of 238 U, 235 U, 232 Th, and 147 Sm when alpha particles (composed of two protons and two neutrons) are expelled from the nucleus and acquire two electrons. These 4 He atoms can be trapped in the crystal lattice and accumulate over geologic time. the fertile materials uranium-238 and thorium-232, respectively. A fertile material, not itself capable of undergoing fission with low-energy neutrons, is one that decays into fissile material after neutron absorption within a reactor. Thorium-232 and uranium-238 are the only two naturally occurring fertile materials. Thorium-232 undergoes an alpha decay, followed by a B-decay.

Thorium 232 alpha decay

Fill in the blank with a number. 232/90 - 11546309 The atomic number of Thorium is 90. So, thorium-232 is represented as 232 90 Th 90 232 Th. The release of an alpha particle See full answer below. Thorium-232 (232 Th) is present in significant amounts in the Earth's crust and is an alpha-emitting radionuclide, which decays to radium-228 (228 Ra), which is a beta emitter with a half-life of about six years; it emits no significant gamma radiation. The 4n chain of Th-232 is commonly called the Thorium Series.

Thorium-232, although radioactive, is found in the materials of some lantern mantles. As already stated earlier, radiogenic radionuclides are part of three decay series, which all start with decay of primordial isotopes of uranium (235 U, 238 U) and thorium (232 Th). Interestingly, each series contains a radioactive isotope of radon, namely, actinon (219 Rn), thoron (220 Rn), and radon (222 Rn) and ends with a stable isotope of lead.
