what protects us from gamma rays?
Several things protect us from gamma rays:
1. Earth's atmosphere: The Earth's atmosphere shields us from gamma radiation coming from space. The atmosphere contains molecules that absorb and scatter gamma rays, reducing the amount that reaches the Earth's surface.
2. Earth's magnetic field: The Earth's magnetic field helps to block charged particles, including some gamma rays, from reaching the surface.
3. Distance from gamma ray sources: Gamma rays emitted from distant objects in space, such as supernovas, can be reduced in intensity by the time they reach the Earth.
4. Shielding: Dense materials such as lead, concrete, and water can be used to make shields to protect us from gamma rays. These materials absorb the energy of the gamma rays and help to reduce their intensity.
