Answer

Beta radiation consists of fast-moving electrons or positrons emitted from the nucleus, while gamma radiation consists of electromagnetic waves, which are highly energetic. Beta particles can be stopped by a few millimeters of plastic or a sheet of paper, whereas gamma rays require dense materials like lead or several centimeters of concrete for significant attenuation. Additionally, beta radiation can cause ionization of atoms, while gamma radiation is more penetrating and can pass through matter with less interaction.
