Answer: The alpha particle is released after alpha radiation.

Step-by-step explanation:

Alpha decay is defined as the decay process in which a heavier nucleus decays into a lighter nuclei. This decay process releases alpha particle which is also known as helium nucleus.

The general alpha decay reaction is given as:


_Z^A\textrm{X}\rightarrow _(Z-2)^(A-4)\textrm{Y}+_2^4\alpha

The particle released will carry a mass of 4 units and carries a charge of +2 units.

Hence, the alpha particle is released after alpha radiation.
