329 views

The strongest radiation naturally occurring on Earth is cosmic radiation. It primarily originates from the sun and outer space and can penetrate the Earth's atmosphere, reaching the surface. Higher altitudes and polar regions experience increased levels of this radiation.

FAQs & Answers

  1. What is cosmic radiation? Cosmic radiation is high-energy radiation that originates from outer space, primarily from the sun and other celestial bodies.
  2. How does altitude affect radiation levels? Radiation levels increase with altitude due to a thinner atmosphere that provides less shielding from cosmic rays.
  3. Are there health risks associated with cosmic radiation? While cosmic radiation exists at low levels on Earth's surface, prolonged exposure at high altitudes (like in airplanes) may pose health risks.
  4. What are other sources of radiation on Earth? Other sources include terrestrial radiation from elements in the ground, radon gas, and radiation from human-made sources.
