The three main types of radioactive decay are:

1. Alpha Decay: This type of decay occurs when an unstable atomic nucleus loses two protons and two neutrons, in the form of an alpha particle. This results in the atomic number of the nucleus decreasing by 2 and the mass number decreasing by 4. Alpha particles have a positive charge and are relatively large, which makes them less penetrating but more damaging to materials they do interact with.

2. Beta Decay: Beta decay is a process where a neutron in the nucleus is converted into a proton and an electron (beta particle). The electron is then emitted from the nucleus. This results in the atomic number of the nucleus increasing by 1. Beta particles are smaller and faster than alpha particles, and can penetrate further into materials.

3. Gamma Decay: In gamma decay, the nucleus transitions from a higher energy state to a lower energy state, releasing the difference in energy as a gamma photon. This type of decay does not change the number of protons or neutrons in the nucleus, but it does result in a more stable nucleus. Gamma radiation is extremely penetrating and can pass through most materials, including human tissue.
