  The strongest radiation on Earth comes from a type of high-energy particles called cosmic rays. Cosmic rays are extremely energetic particles, such as protons and atomic nuclei, that originate from sources outside our solar system, such as supernovae, black holes, and other high-energy events in space. When cosmic rays enter Earth's atmosphere, they collide with atoms and molecules in the air, creating a shower of secondary particles that can be detected by scientific instruments. Some of these secondary particles can be harmful to living organisms, such as ionizing radiation, which can damage cells and increase the risk of cancer. However, it's important to note that the amount of radiation we are exposed to from cosmic rays is generally low and not considered dangerous to human health. Our atmosphere and magnetic field provide a natural shield that protects us from most of the harmful effects of cosmic rays.
