1. Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei during beta decay.
2. Beta particles have a charge of either -1 (for electrons) or +1 (for positrons).
3. Beta particles have a mass that is much smaller than that of an alpha particle, approximately 1/1836th the mass of a proton.
4. Beta particles can penetrate materials to a greater extent than alpha particles, but are still easily stopped by a few millimeters of aluminum or other low-density materials.
5. Beta particles can cause ionization and damage to living tissues if they interact with them, making them potentially harmful to human health.
6. Beta particles are commonly used in medical imaging and radiation therapy, as well as in industrial applications such as thickness gauging and quality control.

Beta particles are high-energy electrons or positrons emitted from the nucleus of an atom during radioactive decay.
Here are some key properties of beta particles:
1. Charge: Beta particles emitted from the nucleus have a charge of either +1 (positrons) or -1 (electrons).
2. Mass: Beta particles have a very small mass, which is only 1/1836 of the mass of a proton.
3. Energy: Beta particles can have a wide range of energies, but they typically have energies between 0.5 and 3 MeV.
4. Penetration: Beta particles can penetrate matter more easily than alpha particles but less easily than gamma rays.
5. Range: The range of beta particles in matter depends on their energy and the density of the material.
6. Deflection: Beta particles can be deflected by magnetic and electric fields.
7. Half-life: The half-life of a beta-emitting isotope is the time it takes for half of the radioactive atoms in a sample to decay.
8. Biological effects: Beta particles can cause ionization and damage to biological tissues.
9. Applications: Beta particles are used in various applications, including:
- Radioactive tracers: Beta particles can be used to track the movement of atoms or molecules in a system.
- Cancer treatment: Beta particles can be used to kill cancer cells.
- Power sources: Beta particles can be used to generate electricity in nuclear batteries.
