L'uranium 236 se  2 Using an emanation electroscope, we observe the radioactive decay of The sequence of decays is known as the Thorium-232 series and goes as follows:  19 Aug 2020 As one of the primordial radioactive isotopes, $$^{232}\mathrm{Th}$$ mainly undergoes $$\alpha $$-decay with a half-life of $$1.402\cdot  As thorium-232 undergoes radioactive decay, it emits an alpha particle, with accompanying gamma radiation, and forms radium-228.

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 decays by alpha decay. Part of the nuclear equation is shown below. Fill in the blank with a number. 232/90 - 11546309 The 4n chain of Th-232 is commonly called the "thorium series" or "thorium cascade".
