Gamma rays are produced both naturally and through man-made processes. Naturally, they originate from cosmic sources like the sun or distant stars, and from radioactive decay. Human activities, such as nuclear reactions and medical imaging, also generate gamma rays.
FAQs & Answers
- What are the natural sources of gamma rays? Gamma rays naturally originate from cosmic sources such as the sun, distant stars, and from radioactive decay of elements on Earth.
- How are gamma rays produced by human activities? Human activities generate gamma rays through processes such as nuclear reactions, medical imaging (like PET scans), and certain industrial applications.
- Are gamma rays harmful to humans? Gamma rays can be harmful to humans due to their high energy, which can damage biological tissues. However, exposure levels are critical, and controlled medical use is typically safe.
- Can gamma rays be shielded? Yes, gamma rays can be shielded using dense materials like lead, concrete, or specialized barriers to reduce exposure and protect against their harmful effects.
