Unleashing the Power of Gamma Rays: Exploring the Highly Energetic Electromagnetic Waves

💥Gamma rays are the most energetic electromagnetic waves and are produced through the radioactive decay of atomic nuclei.

🌌Gamma radiation is used in various fields, including astronomy, medical diagnosis, sterilization, and cancer treatment.

👩‍🔬Astrophysicists define gamma radiation as any radiation with an energy above 100 kilo electron volts, while physicists define it as high-energy photons released by nuclear reactions.

📊Gamma rays can penetrate paper and aluminum, making them useful for detecting leaks, studying gemstones, and measuring thickness.

⚠️Gamma rays are a form of ionizing radiation, which can be harmful and poses health risks if not properly shielded or controlled.

What are gamma rays?

—Gamma rays are high energy photons, the most energetic electromagnetic waves, emitted by the radioactive decay of atomic nuclei.

How are gamma rays used in industry?

—Gamma radiation is used in industry for sterilizing food, detecting leaks in pipes, and ensuring the correct thickness of materials like paper or metal.

Can gamma rays be used for medical purposes?
