The decay is:
Bi-187------------------Tl-183
An alpha particle
There are a number of radioactive isotopes of copper, choosing 66Cu as on that undergoes negative beta decay, the equation is: 2966Cu --> 3066Zn + -10e Where e represents the beta particle, which can also be viewed as an electron.
The equation for the alpha decay of 222Rn is: 86222Rn --> 84218Po + 24He Where He represents the alpha particle, which can also be viewed as a Helium nucleus.
Product of radioactive decay 42He is an alpha particle
The equation for the beta decay of 137Cs is: 55137Cs --> 56137Ba + -10e where the -10e is a negative beta particle or electron.
92U238 --------> 90Th234 + 2He4
alpha particle
An alpha particle itself is not radioactive, but it is the result of a type of radioactive decay called (obviously) alpha decay. The alpha particle is actually a helium-4 nucleus, and it will eventually pick up a pair of electrons and become an atom of that inert or noble gas.
