* Low-energy beta particles (less than 1 MeV): These can travel only a few millimeters in air. Think of the thickness of a piece of paper.
* Medium-energy beta particles (1-10 MeV): These can travel a few centimeters in air. Think of the thickness of your hand.
* High-energy beta particles (over 10 MeV): These can travel a few meters in air. Think of the length of a small room.
Factors Affecting Range:
* Energy: The higher the energy of the beta particle, the farther it will travel.
* Density of the material: The denser the material, the shorter the range. Air is relatively low density, which is why beta particles can travel farther in air than in other materials.
Shielding Beta Particles:
* Thin layers of material: Beta particles can be stopped by thin layers of materials like aluminum, plastic, or even clothing.
* Water: Water is a good absorber of beta radiation.
Important Note: While beta particles can travel a significant distance in air, they lose energy as they travel. This means they become less harmful the farther they travel.
