Alpha Particles: These are positively charged particles consisting of two protons and two neutrons. They are emitted by some radioactive materials such as uranium and can be stopped by a sheet of paper or clothing.
Beta Particles: These are high-energy, high-speedelectrons emitted by certain types of radioactive atoms. They can penetrate living tissue but can be stopped by a layer of clothing or a few millimeters of a substance such as aluminum.
It is also helpful to practice solving problems related to radiation dose, shielding effectiveness, and safety calculations.
Remember to always follow safety guidelines and regulations when working with ionizing radiation, and seek guidance from qualified professionals when conducting experiments or handling radioactive materials.
The student demonstrates an understanding of motions, forces, their characteristics, relationships, and effects by explaining that different kinds of materials respond to electric and magnetic forces (i.e., conductors, insulators, magnetic and non-magnetic materials).
