Study Notes
Cosmic Rays
- Cosmic rays are high-energy particles that come from outer space and interact with the Earth's atmosphere and living and non-living matter on the Earth's surface.
- They generate nuclear changes in atoms, such as radioactive transformations.
- They catalyze chemical processes in organic and inorganic materials.
- They affect cellular reproduction and biological growth.
- They influence cloud formation and other weather phenomena.
Interaction with Matter
- Gamma rays have very high energy but are not very interactive with ordinary matter.
- The interaction of gamma rays with matter is used in many applications, including:
- Medical imaging
- Inspection of industrial materials, where gamma rays can be measured to determine the composition and properties of materials.
Characteristics of Gamma Rays
- Gamma rays can penetrate deeply into matter.
- They are used to inspect the internal structure of materials.
- They can cause ionization and radiation damage to living tissues and materials.
Applications of Gamma Rays
- Gamma rays are used in medical imaging to visualize internal structures of the body.
- They are used in industrial applications to inspect materials and determine their composition and properties.
- They are used to sterilize medical instruments and equipment.
