Alpha particles are the least penetrating, requiring minimal shielding, typically a sheet of paper or the outer layers of human skin can stop them. Beta particles are more penetrating than alpha particles but can be stopped by a few millimeters of aluminum. Gamma rays are the most penetrating and require dense materials like lead or several centimeters of concrete for effective shielding.
