When an isotope undergoes radioactive decay, the types of emissions that mostly occur include:

1. Electrons: These are emitted during beta decay. In this process, a neutron in the nucleus of the atom is transformed into a proton, and an electron is emitted.

2. Gamma-ray photons: These are high-energy photons emitted by a decaying nucleus. Gamma decay usually follows alpha or beta decay, where the daughter nucleus reaches a lower energy state by emitting a gamma photon.

3. Neutrons: These are emitted during neutron emission. It's a type of radioactive decay where an unstable nucleus emits a neutron.

4. Helium nuclei: These are emitted during alpha decay. An alpha particle is identical to a helium nucleus, consisting of two protons and two neutrons.

Heavy nuclei, protons, and infrared photons are not typically emitted during radioactive decay.
