Cosmic radiation permeates all of space, the source being primarily outside of our solar system. The radiation is in many forms, from high speed heavy particles to high energy photons and muons. The upper atmosphere interacts with many of the cosmic radiations, and produces radioactive nuclides.They can have long half-lives, but the majority have shorter half-lives than the primordial nuclides.ome of the major streets of the surrounding cites have radiation levels as high as 0.13 mrad/hr (1.3 Gy/hr), which is more than 10 times the normal background. Another high background area in Brazil is the result of large rare earth ore deposits that form a hill that rises about 250 meters above the surrounding area.
Full Answer. The sun gives off radiation as well as heat energy. The amount of radiation that the Earth receives depends on the Earth's position and the amount of clouds in the Earth's atmosphere. The radiation given off by the sun affects the Earth's climate patterns and its overall temperature. Solar activity, such as solar flares or sunspots, increases the amount of radiation that is given off by the sun and causes the Earth to have dramatic changes in temperature. Sunlight is an important component ...
