Radium, Thorium, Polonium, Uranium

Explanation:

An alpha particle consists of 2 protons and 2 neutrons. When 2 protons and 2 neutrons are emitted, the radioactive element changes into another element because the proton number(atomic number) changes.
When Radium emits an alpha particle, it turns into radioactive Radon.
