Alpha decay of any radionuclide would reduce the atomic number by 2 and reduce the Atomic Mass number by 4. As such, berkelium would decay by alpha emission to americium.
Note that not all isotopes of berkelium decay by alpha emission. In terms of percentages, the most predominate example is ...
97247Bk --> (T1/2 = 1380 years) --> 95243Am + 24He2+
Alpha decay happens when a radioactive atom emits a particle with two protons and two neutrons. Berkelium, with an atomic number of 97, has 97 protons. So when berkelium undergoes alpha decay, it loses two protons, and becomes an atom with 95 protons, atomic number 95, which is americium. Since a total of four nucleons are emitted in the process, the isotope number is four less then what the original atom had.

No. Decay is the process, radiation is the product.
It is thorium 234.
An alpha particle
92Au 282Xe +13S
It is alpha decay. In the process, an alpha particle(He2+) is released. So, it is called alpha decay.
No. Decay is the process, radiation is the product.
The only possible product of the alpha decay of 92238U is 90234Th.
plutonium-239
It is thorium 234.

Product of radioactive decay 42He is an alpha particle
The intermediate product is neptunium 237 ( a very long-lived radioisotope).

Berkelium is not a commercial product.
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.
Berkelium is not a commercial product.
