Beta particles are high-energy electrons or positrons that can be emitted during radioactive decay. They have a moderate ability to penetrate other materials and can be absorbed by a sheet of aluminum.
To determine if a particle can be absorbed by a sheet of aluminum, you need to understand the properties of each particle and compare them to the properties of aluminum.
Alpha particles:
- Alpha particles consist of two protons and two neutrons (helium nucleus) and are positively charged.
- They are relatively large and heavy compared to other particles.
- Due to their size and charge, alpha particles have a short range and are easily deflected by materials.
- Therefore, they can be easily absorbed by a sheet of aluminum.
Beta particles:
- Beta particles can be either negatively charged electrons (beta-minus) or positively charged positrons (beta-plus).
- They are much smaller and lighter than alpha particles.
- Beta particles have a longer range and can penetrate further into materials.
- However, they can still be absorbed by a sheet of aluminum, but at higher energies and thicknesses.
Gamma particles (gamma rays):
- Gamma particles, or gamma rays, are electromagnetic radiation with high energy and no mass.
- They are similar to X-rays but more energetic.
- Gamma particles have a long range and can penetrate deep into materials.
- Unlike alpha and beta particles, gamma particles are not easily absorbed by aluminum.
- It takes dense materials like lead or concrete to effectively shield against gamma particles.
In summary, while all three particles (alpha, beta, and gamma) can penetrate other materials to varying degrees, only gamma particles cannot be easily absorbed by a sheet of aluminum.
