How Do Alpha Particles Interact with Matter

Electrostatic attraction between the two positively charged of an alpha particle and the single negatively charged of an orbital electrons cause ionizations and excitation events. As the positively charged alpha particle moves through matter, it attracts many orbital electrons leaving a wake of ion pairs.

How do alpha and beta particles interact with matter?

A charged particle (alpha or beta particle) exerts sufficient force of attraction or repulsion to completely remove one or more electrons from an atom. binding energy of the electron.

What happens when alpha particles pass through matter?

A Alpha Radiation. As charged particles, such as alpha particles, move through material, energy is transferred from the radiation to the atoms or molecules that make up the material.
