Other isotopes of Thorium undergo beta decay, but they are not naturally occurring.
The equation for alpha decay of thorium is: 90Th232 -------> 88Ra228 + 2He4 (alpha particle).
Th ------> Pa + an electron (e-) + an antineutrino (ṽe).
If for you electron is "negatron" the thorium isotopes from 233 to 238 have a beta decay to protactinium-233. For other isotopes beta decay is rare and without significance.
232Th------alpha-------228Ra
237Th-------------------------233Ra + 4He
229Th-------alpha particle-----------225Ra

If a uranium-244 atom undergoes alpha decay, it will become an atom of thorium-240. If we wrote an equation, it might look like this:92244U => 90240Th + 24He++The uranium-244 is transmuted into throium-240, and the alpha particle, which is a helium-4 nucleus (and represented as such) emerges at the tail end of the equation.
The equation for the alpha decay of 233Pu:94233Pu --> 92229U + 24He2+where the alpha particle is represented as a helium nucleus.Note that 233Pu decays by alpha decay with a probability of only 0.12%. The other 99.88% is Beta+ decay.
Lead-210 decays by alpha or beta decay. The equation for the alpha decay of 210Pb is: 82210Pb --> 80206Hg + 24He representing the alpha particle as a helium nucleus. The equation for the beta decay of 210Pb is: 82210Pb --> 83210Bi + -10e where the -10e is an electron.
229Th-------alpha particle-----------225Ra
Th-230(alpha)Ra-226.
There are 3 naturally occurring isotopes of Uranium, all decay by alpha to Thorium:238U --> 234Th + 4He235U --> 231Th + 4He234U --> 230Th + 4He

The decay of thorium by alpha decay the resultant nuclide is the element radium. The specific nuclide of radium cannot be determined unless we know which specific nuclide of thorium underwent alpha decay.
daughter element

It is thorium 234.

These are all phenomenons in nuclear physics.
