The 3 main sources of radiation are: 1. Cosmic Rays - Radiation that reaches the earth from outer space. 2. Terrestrial Radiation - Emitted from radioactive materials present in the earth’s crust. 3. Man-Made Sources - Includes medical procedures, industrial applications, and nuclear power plants. Understanding these sources is crucial for effective radiation protection and management.

FAQs & Answers

  1. What is cosmic radiation? Cosmic radiation consists of high-energy particles originating from outer space that reach the Earth's atmosphere and contribute to the natural background radiation.
  2. How does terrestrial radiation occur? Terrestrial radiation is emitted from naturally radioactive materials found in the Earth's crust, such as uranium, thorium, and radon gas.
  3. What are common man-made sources of radiation? Man-made sources of radiation include medical imaging procedures like X-rays, industrial equipment, and nuclear power plants used for energy production.
