upright=1.5|thumb|right|An illustration of the relative abilities of three different types of ionizing radiation to penetrate solid matter. Typical alpha particles (α) are stopped by a sheet of paper, while beta particles (β) are stopped by 3mm aluminum foil. Gamma radiation (γ) is dampened when it penetrates lead.

AI overview

Radiation is energy that travels through space or matter, and it comes in different types with varying abilities to penetrate materials—for example, alpha particles can be stopped by paper while gamma rays require lead shielding. It matters because some forms of radiation are unsafe for humans without proper protection, which is why we use warning symbols and shielding to manage exposure to radioactive sources.
