Types

Alpha Radiation

Low penetration (stopped by paper), high ionization (strongly interacts with matter), consists of 2 neutrons and 2 protons.

Beta Radiation

Moderate penetration (stopped by aluminum), moderate ionization, formed when a neutron is turned into a proton.

Gamma Radiation

High penetration (stopped by lead/concrete), low ionization (passes through most materials without strong interactions), consists of photons.

Ionization Ability

The ease with which a type of radiation can remove electrons from atoms.

Ionization Ability of Alpha Particles

High ionization ability due to being big and highly charged, easily removes electrons.

Ionization Ability of Beta Particles

Moderate ionization ability; they are smaller but still interact with matter.

Ionization Ability of Gamma Particles

Low ionization ability as they have no charge and little or no interaction with matter.
