SOURCES OF RADIATION AT HEIGHT
Solar Radiation: Solar radiation originates from the Sun. It's a combination of various types of electromagnetic radiation, including visible light, ultraviolet (UV) radiation, X-rays, and gamma rays. The Sun is a massive nuclear fusion reactor that continuously emits energy into space. Solar radiation changes over a cycle of about 11 years.
Cosmic Rays: Cosmic rays are also referred to as Galactic Radiation. They are high-energy particles, primarily protons and atomic nuclei, that originate from outside our solar system. Their exact sources are still a subject of ongoing research, but they likely originate from supernovae, black holes, and other energetic astrophysical events. The amount of galactic radiation is relatively stable and predictable.
Man-made radiation: It also known as artificial radiation, refers to radiation that is produced by human activities or technology. This type of radiation is not naturally occurring and is a result of various human-made processes, devices, and materials. Man-made radiation includes both ionizing and non-ionizing radiation. For example, nuclear reactors, nuclear power plants, and radioactive materials used in industry and medicine can emit ionizing radiation. Man-made radiation might exist at high altitudes, but in very small amounts when compared with solar and cosmic radiation.
